Question

Select all of the functions that have a constant rate of change

Answer 1

Hi,

The request actually is to choose functions whose derivative is a constant.

For A, derivative is
`(1)/(2\sqrt x)`, which is not constant.

For B, derivative is 2ˣ·ln2, which is not constant.

For C, derivative is 0, which is a constant.

For D, derivative is 1, which is a constant.

So, you can choose C and D.

Have you understood ?
