Answer:
[tex]f^2\left(x\right)=16[/tex]
Step-by-step explanation:
Considering the function
[tex]\:f\left(x\right)=4[/tex]
if
[tex]\:f\left(x\right)=4[/tex]
then the square of a function [tex]f(x)[/tex] is
[tex]f^2\left(x\right)=\left(4\right)^2[/tex]
as [tex]4^2=16[/tex]
so
[tex]f^2\left(x\right)=16[/tex]
Therefore,
