Question

Understanding fundamentals of calculus
(wait for me to type)

Answer 1

I have this problem attached in a screen shot. I worked it a bit differently.

I said y(1+h)-y(1)/h
and literally plugged in 9(1+h)-1.86(1+h)^2-[9(1)-1.86(1)^2
and simplified to 9-1.86H.

When I plugged in 1, I got the 7.14. 2 brings the 5.28. 3 gave me the first answer. What did we do different?
