Answer:
g(2) = 0
Step-by-step explanation:
g(2) is the value of x.
So, we would place g(2) with x:
g(2) = 2(2) - 4
g(2) = 4 - 4
g(2) = 0
If the given function is g(x)=2x-4, the value of g(2) will be 0.
What is a function?The function is described as a particular kind of relationship, and each value in the domain is associated with exactly one value in the range according to the function. They have a predefined domain and range.
It is given that the function is, g(x)=2x-4
We have to find g(2).
In order to find the g(2), substitute 2 as the place of x as,
g(x)=2x-4
g(2)=2×2-4
g(2)=4-4
g(2)=0
Thus, for the given function g(x)=2x-4, the value of g(2) will be 0.

The value of the expression given as (3x + 2.05) + (-x + 1.09) + (2x) + (x) is 5x + 3.14
What are expressions?Expressions are mathematical statements that are represented by variables, coefficients and operators
How to solve the expression?The expression is given as
(3x + 2.05) + (-x + 1.09) + (2x) + (x)

Show all work to identify the asymptotes and state the end behavior of the function
The horizontal asymptote of the function is y=36 and vertical asymptote is x = 6 and its end behavior is f(x)→6.
As the independent variable approaches a certain value, the function approaches asymptotes, but does not cross them. They could be angled, vertical, or horizontal.
ascending asymptotes
There will be a vertical asymptote at x=a if the denominator factor of a rational function, (x - a), is not matched by the same factor in the numerator.
horizontal asymptotes:
When x is large, the value of a rational function approaches the ratio of the highest-degree terms in the numerator and denominator.
Given the function is f(x) = 6x/x-36
limx→±∞ 6x/x-36
= limx→±∞ 6/1-36/x
= 6 ⇒ horizontal asymptote: y = 6
Consider denominator = 0 ↔ x-36 = 0 ↔ x=36
limx→₊₂₅ 6x/x-36
= 6×36/0⁺ = ∞ ⇒ vertical asymptote: x = 36
End behavior of f(x):
As x → -∞ or x → ∞, f(x) → 6.

Lowes carries 3 types of plants. 1/10 of the plants are fruit bearing 1/2 of the plants are flower bearing, the rest are vegetable bearing plants. How many are vegetable bearing plants?
The number of vegetable bearing plants are : 0.45x, where x is the total number of plants.
A fraction in mathematics represents a portion or element of the whole. It represents the appropriate parts of the totality. A fraction is made up of two parts: the numerator and the denominator. The number at the top is the numerator, and the number at the bottom is the denominator. The numerator indicates the number of equal parts that were actually taken, whereas the denominator shows the total number of equal parts in the whole.
Let x be the initial plant population.
Now that 1/10 of plants bear fruit, the quantity of fruit-bearing plants is equal to 0.1x.
Plants remaining then equal x - 0.1x = 0.9x.
Once more, because half of the remaining plants give flowers, the number of flower-bearing plants is equal to 0.5(0.9x) = 0.45x.
As a result, the number of plants left is equal to 0.9x - 0.45x = 0.45x.
Given that all remaining plants produce veggies, the number of plants that do so is equal to 0.45.

Describe or show how to determine the average rate of change between x = 2 and x = 4 for the function f(x) = 2x3 + 1. Include the average rate of change you found in your answer.
The average rate of change on the interval [2, 4] is 56
How to find the average rate of change on the given interval?
Here we have the function:
f(x) = 2x^3 + 1
And we want to find the rate of change on the interval [2, 4].
Remember that for a function f(x) the rate of change on an interval [a, b] is.
R = ( f(b) - f(a))/(b - a)
Then in this case, the rate of change is:
R = [ f(4) - f(2)]/[4 - 2] = ( 2*4^3 + 1 - 2*2^3 - 1)/2 = (4^3 - 2^3) = 56

The probability of someone being 5 feet and 4.2 inched tall is 0.2877
Probability:
Probability means the possibility of occurring the specific even across the total number of event.
Given,
100 people where sampled and their heights were recorded, it was discovered the mean height was 5 feet and 6.3 inches with a standard deviation of 3.75 inches.
Here we need to find the the probability of someone being 5 feet and 4.2 inches tall.
From the given details, we know that,
n = 100
mean (ч) = 5 feet and 6.3 inches
standard deviation (σ) = 3.75 inches
We know that the formula to find the probability is,
P = (x - ч)/σ
But here we have used the different measurement for each. So, the first step is convert them into inches.
So,
5 feet and 6.3 inches = 60 + 6.3 inches = 66.3 inches.
Similarly 5 feet and 4.2 inches = 64.2 inches.
So, the probability is,
P (X < 64.2) = (64.2 - 66.3)/3.75
P (X < 64.2) = -0.56
Based on the standard normal table to conclude that:
P (X < 64.2) = -0.56 = 0.2877
Therefore, the probability of someone being 5 feet and 4.2 inches tall is 0.2877.

C = rolling a multiple of 3
So,

P(B)=[tex]\frac{3}{6} =\frac{1}{2}[/tex]
P(C) = [tex]\frac{2}{6} =\frac{1}{3}[/tex]

y=8800(1.573)^x
y=8800(1.573)

The given exponential function represents the growth in function with a percentage increase as 57.3%.
Given we have the exponential function as :
y=8800(1.573)ˣ
it is in the form of: y=k.aˣ
therefore, if a>2 then the function represents growth.
and if a<1 then the function represents decay.
now, x=1.573
1.573 > 1
so, the function represents change in growth.
therefore, 1.573 - 1
