Question

find f'(-3), if f(x)=(2x^2-7x)(-x^2-7). round your answer to the nearest integer

Answer 1

just expand f(x)
take derivative
replace x =-3 in its derivative
Done

Answer 2

ok but I end up with a really bigggggggggg number

Answer 3

Show your work, please

Answer 4

ok here:
f(-3)=(2(-3)^2-7(-3))(-(-3)^2))
f(-3)=-624
I know I did something wrong

Answer 5

hey, your question is to find \(f'(-3)\) not \(f(-3)\)

Answer 6

\(f(x) = (2x^2-7x)(-x^2-7)\)
Use FOIL to expand it, what do you have?

Answer 7

-2x^4+49x

Answer 8

Nope
