google classroom microsoft teams
the tables below show some inputs and outputs of functions $g$ and $h$.
$x$ 1 4 9 16 25 36
$g(x)$ 1 2 3 4 5 6
$x$ 5 10 15 20 25 30
$h(x)$ 1 2 3 4 5 6
evaluate.
$(h \circ g)(25) = \square$

Explanation:

Step1: Find g(25) from table

From the table for $g(x)$, when $x=25$, $g(25)=5$

Step2: Compute h(g(25))

Substitute $g(25)=5$ into $h(x)$. From the table for $h(x)$, when $x=5$, $h(5)=1$
