Question

Can someone help with this?

Answer 1

Recall that the derivative is the limit of the difference quotient.
\[\lim_{h\to0}\frac{f(x+h)-f(x)}{h}\]
Use the smallest possible value for h to get the best approximation

Answer 2

Let h = -0.02
\[\frac{f(2+(-0.02)) - f(2)}{-0.02} = \frac{f(1.98)-f(2)}{-0.02}=\frac{5.10-5}{-0.02}=-5\]

Answer 3

okay thanks!!
