Answer:
40
Step-by-step explanation:
85% is .85
go through and multiply .85 by each number and see which one = 34
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)
