Question

If f(x) = x2 + 5 and g(x) = 34, then find f(g(x))?

Answer 1

You have the following functions:

$\begin{gathered} f(x)=x^2+5 \\ g(x)=34 \end{gathered}$

In order to evaluate f(g(x)), replace the expression for g(x) where x is in the function f(x), just as follow:

$f(g(x))=(g(x))^2+5=(34)^2+5=1161$

Hence, f(g(x)) is 1,161
