Using the critical point concept, it is found that a = -3 and b = 7.
<h3>What are the critical points of a function?</h3>
- The critical points of a function are the values of x for which:

In this problem, the function is:

Hence, the derivative is:

Then:







Since the critical point is at x = 2, we have that:




Then:

Critical point at (2,3) means that when
, then:
