Answer:
g(x) = -x +9
Step-by-step explanation:
Reflecting across the y-axis involves changing the sign of x, so the reflection of f(x) is ...
... g(x) = f(-x) = (-x) +9
The appropriate choice is ...
... g(x) = -x+9
The equation which describes the function g is:
The graph of the function f(x) is given by:
Now, we know that the transformation of the function f(x) when the graph is shifted across the y-axis then it is given by:
f(x) → f(-x)
This means that:
g(x)=f(-x)
i.e.
g(x)= -x+9
Hence, the equation which will represent the graph of the function g(x) is given by:
(a) Find the height of the ball (in feet) above the ground 2 s after its released.
That's just h(2)
h(2) = -16(2²) + 80(2) + 4 = -64 + 160 + 4 = 100
Answer: 100 feet
(b) Find the height of the ball (in feet) above the ground 4 s after its released.
That's just h(4)
h(4) = -16(4²) + 80(4) + 4 = -256 + 320 + 4 = 68
Answer: 68 feet
The answer is C. I have the work for it in the image bellow
Hope this helped!
