Evaluate the function

Question

Hi... how do i solve this... whats the answer...?

Im so confused... even though it looks easy

f(x+h)= (square root symbol is supposed to be here) x-1 (these numbers are inside of it)

Answer 1

Based on the information provided by you,

If f(x) = √(x-1)

then f(x+h)= √ (x+h-1) substitute (x+h) for x
