Answer:

First graph

Step-by-step explanation:

First off, the graph opens up because <em>a</em><em> </em>is positive. Second, the parent function of the quadratic graph is \displaystyle y = x^2,and the greater the WHOLE NUMBERS [vertical stretch (<em>a</em>)] get, the slimmer the parabola gets, and the more you increase the DEGREE evenly [anything ending in 0, 2, 4, 6, and\or 8], the more flat, U-shaped the parabola becomes.

I am joyous to assist you anytime.

Answer:

The first graph is the correct one.

Step-by-step explanation:

y = 2x^8

The degree of x  is even (=8) so the equation is an even function and will be symmetrical about the y-axis. So this rules out the second graph.

The coefficient (2) of x^8 is positive so all values y values will be positive.

Therefore it is the first graph.

write the slope- intercep form of the equation of the line through tje given point perpendicular to tje the given line. (point):
Sergeeva-Olga [200]
Perpendicular lines have gradients that multiply to give -1 
So, the gradient of the line we need is -1/0.2 = -5
If we have the gradient and a point in the line, we can work out the equation using the formula:
y - y1 = m(x - x1)
where m = gradient, y1 = y-coordinate and x1 = x-coordinate of the same point
So, we substitute in our values, and we get:
y - -8 = -5(x - -7)
y+8 = -5x-35
y = -5x-43

Hope I helped! xx

Answer:

C.g(x) = 5x²

Step-by-step explanation:

To find the equation for the function g(x), use the format for a quadratic equation. Without any up/down and left/right shifts, the form is y = ax².

Substituting "x" and "y" into the equation tells you if a point is on the graph.

"a" tells you the vertical stretch (greater than 1) or compression (greater than 0, less than 1).

In f(x) = x², a = 1 even though it's not written.

<u>Use the point (1, 5) on g(x) and substitute it</u> into the form for a quadratic function. Remember points are (x, y), so x = 1 and y = 5.

g(x) = ax²    

y = ax²       In function notation, g(x) replaces the "y". Switch it back to "y".

5 = a(1)²     Substitute x = 1 and y = 5

5 = a(1)     Solve the exponent first. (1)² = 1

5 = a         When you multiply "a" by 1, the answer is just "a".

a = 5         Solved for "a". Put variable on left side for standard formatting.

With the quadratic form, substitute "a" into g(x).

y = ax²

g(x) = 5x²
