Question

If f(x)=6x - 8, g(x)=1/2x, and h(x)=x+4, find (f o g o h)(x). My answer is 3x^3 + 8x^2 - 16x. Is it correct?

Answer 1

f(x)=6x - 8, g(x)=x/2, and h(x)=x+4, find fgh(x)??

Answer 2

yes

Answer 3

\[fg(x+4)\]
\[f(\frac{1}{2}(x+4))\]
\[f(\frac{x+4}{2})\]
\[6(\frac{x+4}{2})-8\]
3x+12-8
3x+4
