Question

For f(x) = 3x + 1 and g(x) = x^2 - 7, find f(g(4)).

Answer 1

First, let's find g(4). After we find it, we can substitute the value into
`f(x)`.

To find g(4), we need to substitute x = 4 into the function
`g(x)`, as shown below:

`g(x) = x^2 - 7`

`g(4) = 4^2 - 7`

`g(4) = 9`

Now that we have found g(4) = 9, we can substitute this value in for
`x` in
`f(x)`.

`f(x) = 3x + 1`

`f(9) = 3(9) + 1`

`f(9) = 28`

f(g(4)) is equal to 28.
