Question

If f(x)=x²-6 x+2 and g(x)=-2x, find the following composition. (g ° f)(5)
(g ° f)(5)=

Answer 1

What the composite function in the question is actually trying to explain is;

• 
  `(gof)(x)=g(f(5))`

First of all, in the function
`F(x)`, we will find a result by writing
`5` where we see the letter
`x`.

• 
  `F(5)=5^2-6(5)+2=-3`

We will write this result in the
`G(x)` function where we see the letter
`x` and we will get the result.

• 
  `G(-3)=-2(-3)=6`
