The approximate slope of the quadratic function y = 4 + 9x + 3x² when x = 1 is 15

How to calculate the function?

The approximate slope of the quadratic function y = 4 + 9x + 3x² when x = 1 will be calculated thus:

First we will find the derivative with respect to x. This will be:

9 + 6x

Since x = 1

9 + 6x = 9 + 6 = 15
