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:
