Given: f(x) = x 2 + 2x + 1, find f(x + h) and simplify.

x^2+h^2+ 2hx + 2h + 2x + 1

Step-by-step explanation:

Plug x+h for x

(x + h)^2 + 2(x + h) + 1

x^2 + 2hx + h^2 + 2x + 2h + 1

x^2+h^2+ 2hx + 2h + 2x + 1

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
