The minimum occurs at the function's y-intercept.
O D.
Answers
Answer:
B. The maximum occurs at the function's x-intercept.
Step-by-step explanation:
Given table:
[tex]\large\begin{array}{| c | c | c | c | c | c | c |}\cline{1-7} x & -5 & -4 & -3 & -2 & -1 & 0\\\cline{1-7} g(x) & -1 & 0 & -1 & -4 & -9 & -16\\\cline{1-7}\end{array}[/tex]
From inspection of the table, we can see that:
[tex]g(-5) = -1[/tex] and[tex]g(-3) = -1[/tex]This indicates symmetry.
The line of symmetry is the mid-point between the two x-values.
Therefore, the line of symmetry is x = -4
The vertex (minima/maxima) is on the line of symmetry, therefore the vertex is at (-4, 0). As the function decreases as x → 0, the vertex is a maximum.
As the y-value of the vertex is 0, the maximum occurs at the function's x-intercept.
Answer:
B
Step-by-step explanation:
Finding the line of symmetry :
⇒ Two x-values have the same y-coordinate → (-5) and (-3)
⇒ This means the symmetry is exhibited and it lies between these 2 x-values
⇒ Line of symmetry : x = -4
=============================================================
Now, on plotting these points on a graph we see that this graph has a negative coefficient.
⇒ This means this graph will have a maximum point as the vertex
⇒ The vertex lies on the line of symmetry, hence the vertex (according to the graph and table) is (-4, 0)
Hence, we can say that the maximum occurs at the function's x-intercept.

The end behavior of the graph of f(x) = -0.25x2 - 2x + 1 is that A) As x increases, f(x) increases. As x decreases, f(x) decreases.
What is the end behavior about?The end behavior of a function f tells us that the way that the graph function behaves at the "ends" of the x-axis.
Note that the end behavior of a function tells the trend of the graph and in this graph, f(x) -----> +∞ as x----> -∞ (as the value of x decreases the value of f(x) increases) and f(x) -----> -∞ as x----> +∞ (as the value of x increases the value of f(x) decreases).
Therefore, The end behavior of the graph of f(x) = -0.25x2 - 2x + 1 is that A) As x increases, f(x) increases. As x decreases, f(x) decreases.

The answer is 97
Step-by-step explanation:
According to PEMDAS, we will solve the multiplication first. 2 × 42 is 84. Next, we will add or subtract from left to right. 9 + 84 + 6 – 2 is 97, the answer to our problem.
9 + 2 × 42 + 6 - 2
Multiply 2 and 42 to get 84.
9 + 84 + 6 - 2
Add 9 and 84 to get 93.
93 + 6 - 2
Add 93 and 6 to get 99.
99 - 2
Subtract 2 from 99 to get 97.

what are the key features of the graph of a trigonometric function? How do you find them from a graph or an equation?
Answers
Answer:
The basic sine and cosine functions have a period of 2π. The function sin x is odd, so its graph is symmetric about the origin. The function cos x is even, so its graph is symmetric about the y-axis. The graph of a sinusoidal function has the same general shape as a sine or cosine function.
They are the three x-intercepts, the maximum point, and the minimum point. All of these are on your unit circle. The values of sin x correspond to the y-values, so those key points are (angle, y-value) or (0,0), (π/2, 1), (π, 0), (3π/2, -1), (2π, 0).

Step-by-step explanation:
650065 = (a² + 1)(c² + 1)
and
650065 = (ac - 1)² + (a + c)² = the sum of 2 squared numbers (ac - 1)² and (a + c)².
we see that 5 and 13 and therefore 5×13=65 are all factor of 650065. and then 650065/65 = 10001.
and we know that 65 = (64 + 1) = (8² + 1)
and 10001 = (10000 + 1) = (100² + 1)
so, a = 8, c = 100
that means the 2 squared numbers summing up to 650065 are
(ac - 1)² = (8×100 - 1)² = 799² = 638,401
(a + c)² = (8 + 100)² = 108² = 11,664
650,065 = 638,401 + 11,664 = 799² + 108²

This is because the parabola goes down which means a is negative and the y intercept is -1 which means the c in the equation is -1

What is an equation?"It is a mathematical statement which consists of equal symbol between two algebraic expressions."
What is parabola?"It is a curve, such that a point on the curve is equidistant from a fixed point, and a fixed line. "
For given question,
The graph describes the parabola.
The parabola opens downward, so the equation of the parabola would be,
[tex]y=-x^{2}[/tex]
We know that, for a function f(x) is transformed to f(x) + c if c > 0 then the graph of the function moves up by c units.
if c < 0 then the graph of the function moves down by c units.
As the graph of the parabola moves down by 1 unit, the equation of the parabola would be,
[tex]y=-x^2+1[/tex]
Therefore, the equation that describes the graph is [tex]y=-x^{2} +1[/tex]
