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

  1. 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.

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

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

  1. Recall that the derivative of is .
