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

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.
