Answer 1

HI!!

Answer 2

9

Answer 3

do you have to do this by hand?

Answer 4

no, I just need to find the answer. there was no restriction on how

Answer 5

f(x)=9x0.2−6x67

Answer 6

or can you use the power rule so that the derivative of \[f(x)=-12x^2+9x+6\]is \[f')x)=-24x+9\]

Answer 7

so where do I go from there? the whole topic as a whole is foreign to me. I didn't understand the lesson.

Answer 8
