How many turning points are in the graph of the polynomial function?
a. 4 turning points
b. 5 turning points
c. 6 turning points
d. 7 turning points

Option B is correct that is 5 turning points

Step-by-step explanation:

Turning points are those points where graph changes its direction from upward to downward

And downward to upward

We can see that graph is changing its direction at  5 different points and the points are

(-5,6) ,(-3,-3) ,(0.5,0.5) ,(3,2.5) ,(5,5)

Hence, option B is correct that is 5 turning points.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
