Question

Need help on precalculus

Answer 1

-3 units

Explanation:

You can solve this problem using the equation
`rate = (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=(-6)/(2)=-3`
