Answer: b. y=5
Step-by-step explanation:
Take the cube root of both sides.
![y=\sqrt[3]{125}](https://tex.z-dn.net/?f=y%3D%5Csqrt%5B3%5D%7B125%7D)
Calculate.
y=5
Answer:
D
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is

Here { a, b ] = [ - 1, 2 ], thus
f(b) = 4 ← from (2, 4 )
f(a) =
← from (- 1,
) , thus
average rate of change =
=
=
→ D
