Let f(x)=xx < x squared work out and write in its simplest form f(x+2)+1 Hello, I assume that your function is: $\displaystyle f(x) = x^2$ To calculate f(x+2) you have to plug in the term (x+2) instead of x into the given equation: $\displaystyle f(x+2)+1 = (x+2)^2+1 = x^2+2\cdot 2 \cdot x + 2^2 + 1 = \boxed{x^2+4x+5}$
