Question

If f(x)=4 then what does f^2(x)=?

Answer 1

Answer:

$f^2\left(x\right)=16$

Step-by-step explanation:

Considering the function

$\:f\left(x\right)=4$

if

$\:f\left(x\right)=4$

then the square of a function $f(x)$ is

$f^2\left(x\right)=\left(4\right)^2$

as   $4^2=16$

so

$f^2\left(x\right)=16$

Therefore,

• $f^2\left(x\right)=16$
