If $g(x) = x^2$ and $f(x) = 2x - 1$, what is the value of $f(g(2))$?
To evaluate $f(g(2))$, I need to first find $g(2)$ and then plug it into $f(x)$. $g(2) = 2^2 = 4$, so $f(g(2)) = f(4)$. To find $f(4)$, I need to substitute $x = 4$ into $f(x) = 2x - 1$. $f(4) = 2(4) - 1 = 8 - 1 = 7$. So the value of $f(g(2))$ is 7.
