Question

What are the critical values, if any, of `f(x)=15x+17`?

Answer 1

No critical values here.

Explanation:

Critical values occur at points where the derivative is zero.

In this case, `f'(x)=15!= 0 AAx in RR` so there are no critical points.

This is also clear from the graph, being a linear function hence a straight line.
