Question

Need help on precalculus

Answer 1

Answer:

-3 units

Step-by-step explanation:

You can solve this problem using the equation $rate = \frac{change}{time}$.

First identify the change with the equation $change= f_{final} - f_{initial}$. Since you are finding the rate of change from -1 to 1, the equation will be $change = f(1)-f(-1)$ which is 0-6 or -6.

Next, find the time, or in this case, change in x. This will be $x_{final} -x_{initial}$ or

1-(-1), which is 2.

Finally, plug it all in:

$rate=\frac{-6}{2}=-3$
