Question

Please help! Let f(x)=x^2+5x, g(x)=6-2x, h(x)=2/x-3; find the following value. 4 g(-2 x)=?

Answer 1

First of all we only have to use g
since we are asked to simplify 4g(-2x)

Answer 2

We are given
\[g(x)=6-2x\]
so
\[g(-2x)=6-2(-2x)\]

Answer 3

\[4g(-2x)=4(6-2(-2x))\]

Answer 4

You can simplify this right?
