Step-by-step explanation:
<h3>Average rate of change:</h3>
To find the average rate of change, we have divide the change in y of f(x) , by the change in x(input).
a = 4 ; f(a) = -17
b = 6 ; f(b) = -37
![\sf Average \ rate \ of \ change = \dfrac{-37-[-17]}{6-4}](https://tex.z-dn.net/?f=%5Csf%20Average%20%5C%20rate%20%5C%20of%20%5C%20change%20%3D%20%5Cdfrac%7B-37-%5B-17%5D%7D%7B6-4%7D)
Answer:
Step-by-step explanation:
Please use " ^ " to indicate exponentiation: g(x) = 4(x - 2)^2 - 4
The axis of symmetry comes from that "(x - 2)." It is x = +2.
The axis of symm. of f(x) is discernable in the diagram; that axis of symmetry is x = -2.
