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
I don't know but I think it is B) The slope is negative, and a linear model is a good fit for the data.
I think that person above me should be your answer
Seems to be a typo:
If you meant to say just "an article" then it would be 1/3 of the article per minute.
If it is supposed to say "half of an article" he would have read 1/6 of the article per minute. Hope this helps!
