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:

Answer:
You can't find y in this way
Step-by-step explanation:
You should know the value of x
But you can say
Y=7x
Answer:
angle B = 33.42
Step-by-step explanation:
take angle B as reference angle
using tan rule
tan B = opposite/adjacent
tan B = 6/9
tan B = 0.66
B = 
B = 33.424
B = 33.42
