Answer:
1 answer which would be -5+5 which =0
Step-by-step explanation:
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:
No
Step-by-step explanation:
A relation is a function if every x-value has exactly one y-value.
Because the x-value 1 has two y-values (-3 and 3), the relation is not a function.
Plotting (1, -3) and (1, 3) will produce a vertical line that intersects the function at two points.
Therefore, the relation is not a function.
Hope that helps.
