Take the derititve

f'(x)=3x^2+6x-24
set to zero
0=3(x^2+2x-8)
0=3(x-2)(x+4)
at x=2 and -4

those are where the min and max are

ok so

to the lft of -4, the sign is positive
betweeen -4 and 2, the sign is negative
tothe right of 2 the sign is positive


max=sign changef from (+) to (-)
min=sign change from (-) to (+)

so max at x=-4 and min at x=2

find x=2, the value is -28

answer is C

Is a quadratic sequence (2,3,6,11) arithmetic, geometric, or neither?
Karolina [17]

Answer:

Neither

Step-by-step explanation:

It's neither. The terms do not differ (which means you add the same number to each term) by any constant amount.  (Arithmetic)

The terms do not have a common number that you multiply the present term to get the next term. (Geometric)

So this one is neither.
