If f(x) = 2x^2 - x +2 what is f(a+h)
f(a+h) = 2(a+h)^2 -(a+h) + 2
= 2a^2 +4ah +2h^2 -a-h +2

Anywhere there is an (x), plug in (a+h) and simplify
2(a+h)^2 - (a+h) +2
2(a^2+2ah+h^2)-a-h+2
2a^2+4ah+2h^2-a-h+2

f(a+h) = 2*(a+h)*(a+h) - (a+h) + 2 = 2*a*a + 4*a*h + 2hh - a - h + 2
Answer:2*a*a + 4*a*h + 2*h*h - a - h + 2
OR
2a^2+4ah+2h^2-a-h+2,
what is the same.

Just replaces the x's with a+h
2(a+h)^2-(a+h) +2

Just substitute x = a+h in the equation.
f(a+h) = 2(a+h)^2 - (a+h) + 2
Good luck!
