Question

f(x)=-6x-1 and g(x)=4x^2 find the solution for (fg)(x)

Answer 1

\((fg)(x)=f(x)*g(x) = (-6x-1)(4x^2)\)

Answer 2

then you distribute?

Answer 3

correct

Answer 4

or leave it alone... either way.

Answer 5

then if I distribute it becomes -24x^2-1?

Answer 6

\(4x^2(-6x-1)=(4x^2)(-6x)-(4x^2)*1=-24x^3-4x^2\)

Answer 7

are you positive because that doesn't seem like what I got the other day
