Step-by-step explanation:

Answer:BE is equal to 72.
Step-by-step explanation: They are similar triangles. We know CD and BC. So we can find the comparison between the two. And we see that BC x 7 = CD. So the same will be said for BF and FE. We have BF is equal to 9. So 9 x 7 = 63. However, now we need to add the two together in order to get BE. Because BF + FE = BE. So 9 + 63 = 72
Answer:A
Step-by-step explanation:
Given

Turning Point is the point where the graph changes its nature i.e. either increasing to decreasing or decreasing to increasing
to find turning point

For critical point
F'(x)=0

x+2=0
x=-2

thus
(-2,-4 ) is the turning Point where Function changes its nature
