First plug in (x+h) for x in the function.
f(x+h)= 2(x-h)^2-3(x-h) = 2(x^2-2xh+h^2)-3x-3h =
2x^2-4xh+2h^2-3x-3h - 2x^2 +3x =
(-4xh +2h^2-3h)/h
-4x +2h-3
Answer:
Step-by-step explanation:
A = -2.2
E.
( -2.1 ) + ( - 0.1 )
( -2.1 ) - 0.1. <—— over there, you will see that + is gone and the - has moved down, I done that because + plus with - equals to -.
-2.1
-0.1
———-
-2.2
