Question

Let f(x)=x-3 and g(x)= x^2 find f(g(4))

Answer 1

Answer: 13 your welcome boo lol

Answer 2

the value of
`f(g(4))` is, 13

Explanation:

Given the function:

`f(x) = x-3`

`g(x) = x^2`

we have to find the value of
`f(g(4))`;

`f(g(x)) = f(x^2)`

Replace x in place of
`x^2` in the fucntion f(x) we have;

`f(g(x)) =f(x^2) = x^2-3`

⇒
`f(g(x)) = x^2-3`

Put x = 4 we have;

`f(g(4)) = 4^2-3=16-3 =13`

Therefore, the value of
`f(g(4))` is, 13
