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
sign chart
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
2. 4th degree so quartic (qua, like quad or quadrilatal)
By giving the answer and the explanation!
Hope this helps! :)
Answer:

Answer:
= .75 gallons or 3 quarts
Step-by-step explanation:
Known
Problem:
4 gallons 2 quarts - 3 gallons 3 quarts
⇒ 2 quarts: 0.5 gallons
⇒ 3 quarts: 0.75 gallons
Add on both sides
4 + 0.5 = 4.5 gallons
3 + 0.75 = 3.75 gallons
This leaves the equation at:
- 4.5 gallons - 3.75 gallons
This equals 3 quarts or 0.75 gallons.
Bisected means cut in half. half of 62 is ,31
