Question

f(2)=x+2
send me the answers of ur​

Answer 1

How does the location of a power in a function adjust its result?

For example if f(x)=2x

I assume that f(x2) would equal 2x2.

What I am unsure about is if f2(x) means f(x)×f(x) or f(f(x)). So would the final answer be (2x)(2x)=4x2 or 2(2x)=4x.

And is f(x)2 the same as f2(x)
