The function that associates each number with its square is the following function:
[tex]h(x)=x^2[/tex]For each number x, we will get the square of it as the result.
In this case, since we need h(4), that means that:
[tex]x=4[/tex]We substitute this into h(x) and we get the following result:
[tex]\begin{gathered} h(4)=4^2 \\ h(4)=16 \end{gathered}[/tex]Answer: h(4) = 16
