Question

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

Answer 1

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

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`
