The domain of f(x) = 5x - 7 is {x | x is a real number} and this can be denoted as (-∞, ∞) for all x ∈ R.

What is domain?

The domain is the set of all the input values given to a function.

Given is an expression f(x) = 5x - 7, we need to find the domain,

We know that,

The domain of any expression is set to all the real numbers, except where the expression is undefined.

Therefore, the domain is all real numbers.

Also,

The graph of the function will be a straight line without discontinuities.

Hence the domain of f(x) = 5x - 7 is {x | x is a real number} and this can be denoted as (-∞, ∞) for all x ∈ R.

Because the minimum value of f(x) is -1, and the minimum value of g(x) us -25. It comes only once.

Roots are the points on the x - axis or when the x is 0. The roots of f(x) are positive.

f(0) means when x is 0, so f(0) = 3 or 5, and g(0) = -24

the coordinates of the point on the unit circle at the given angle 180 degrees is (-1,0)

The coordinates of the point on the unit circle at the given angle 180 degrees is (-1, 0).

What is a unit circle?

A unit circle is just a circle that has a radius with a length of 1. A unit circle can be used to define right triangle relationships known as sine, cosine and tangent. These relationships describe how angles and sides of a right triangle relate to one another.

The given drawing is the graph of the unit circle on the X – Y Coordinate Axis.

It can be seen from the graph, that the unit circle is defined as having a Radius ( r ) = 1.

Going from Quadrant I to Quadrant IV, counter clockwise, the Coordinate points on the axis of the unit circle are:

(1, 0), (0, 1), (-1, 0), and (0, -1)

This is important to remember when we define the X and Y Coordinates around the unit circle. The Unit Circle has 360°. In the given graph, the Unit Circle is divided into 4 Quadrants that split the unit circle into 4 equal pieces. Each piece is exactly 90°.

From the diagram we can clearly say that the coordinates of the point on the unit circle at the given angle 180 degrees is (-1, 0).

assume f is a one to one function of f(x)= 4-6x find f^-1(-32)​

Answers

Answer:

f^-1(-32)=6

Step-by-step explanation:

Find the inverse of the function f(x)=4-6x:

f(x)=4-6x

y=4-6x

x=4-6y

x-4=-6y

(x-4)/-6=y

-1/6x+2/3=y

y=-1/6x+2/3

f^-1(x)=-1/6x+2/3

Plug in f^-1(-32) for f^-1(x) and simplify:

f^-1(-32)=-1/6(-32)+2/3

f^-1(-32)=16/3+2/3

f^-1(-32)=18/3

f^-1(-32)=6

f(-2) = -3 - 4

f(-2) = -7

Answer:

f(-2) = -7

Step-by-step explanation:

f(-2) means that for every x given in the equation, -2 would be substituted in it's place. Therefore;

[tex]f(-2)=\frac{3}{2} (-2) - 4[/tex]

f(-2) = -3 - 4
