f(x) = 4.4t2
Apply the difference quotient formula:
f(t - ∆t) – f(t) / ∆t
4.4(t + ∆t) –(4.4t2) / ∆t
Somehow the equation above is supposed to reduce to 8.8t however I don’t see how yet. I used an online derivative calculator which shows 8.8t as the answer however what I am being asked to do is apply the difference quotient formula I think to the equation.
I worked the equation to:
4.4t2+4.4∆t2+-4.4t2 / ∆t = 4.4∆t
However I think I must be in error because the answer by the derivative calculator is 8.8t. I need to see how the difference quotient is used because my class did not teach the power rule so I am supposed to apply the difference quotient I believe.
