3-88.

Given each function below, write its slope function. Homework Help ✎

You should know by now that a derivative is a slope function. Notice that this is a linear equation, and linear equations have constant slopes.

Similarly, this is a horizontal line. What is the slope of a horizontal line? That will also be the derivative.

Multiply

by itself three times to get a simple polynomial. Then take the derivative.

Recall that the derivative of

is .
