Question

Use the table below of the function f(x) = x4 − 2x3 to answer this question:

Answer 1

ANSWER

The average rate of change from $x=-1$ to $x=2$  is $-1$

EXPLANATION

The average rate of change from $x=-1$ to $x=2$

$=\frac{f(2)-f(-1)}{2-(-1)}$

From the table,

$f(2)=0$ and $f(-1)=3$.

So we substitute in to the above expression for average rate of change.

$Average\:Rate\:of\:Change=\frac{0-3}{2+1}$

$=\frac{-3}{3}$

$=\-1$

The correct answer is B
