Take the derivitive
f'(x)=6x^2+2x-11
find where f'(x)=0
f'(x)=0 when x=-1.53089 or x=1.19756
we use a sign chart
test values to see where the signs are
(see attachment)
f'(-2)=(+)
f'(0)=(-)
f'(2)=(+)
max happens when sign changes from (+) to (-)
min happens when sign changes from (-) to (+)
according to the chart, max is at -1.53089 and min is at 1.19756
now evaluate the original function for x=-1.53089 and x=1.19756
f(-1.53089)=12.0078
f(1.19756)=-8.30405
max at (-1.53089,12) and min at (1.19756, -8.30405)
I may have rounded off differently, but
answer is 2nd option

Answer:
The volume of a cylinder is 2462 feet³ .
Step-by-step explanation:
Formula
Where r is the radius and h is the height .
As given
Cylinder with height of 4 feet and radius of 14 feet.
h = 4 feet
r = 14 feet
Put all the values in the formula
= 2461.176 feet³
= 2462 feet³ (Approx)
Therefore the volume of a cylinder is 2462 feet³ .
Answer:
Reason: The graph shows all values that are z = -10 or larger.
The closed endpoint at -10 indicates we include it with an "or equal to".
If it was an open hole endpoint, then we'd say z > -10 instead.
