Question

Given that F(x) = x ^2 + 2, evaluate F(1) + F(5).

Answer 1

It simplifies to 6, therefor the answer is 6.

Answer 2

Part 1
Let's solve for f.fx=x2+2Step 1: Divide both sides by x.fxx=x2+2xf=x2+2xAnswer:f=x2+2x

Part 2
Let's simplify step-by-step.f(1)+f(5)=f+5fCombine Like Terms:=f+5f=(f+5f)=6fAnswer:=6f
