Chapter 9.3, Problem 20E

(a)

To determine

To calculate: The value of $f^{\prime }\left(-1\right)$ using $\frac{f\left(a+h\right)-f\left(a\right)}{h}$ with $h=0.0001$, for the function, $f\left(x\right)=2x^3-11x+9$.

(b)

To determine

To calculate: The slope of the straight line obtained when the graph of the function, $f\left(x\right)=2x^3-11x+9$, is plotted and it is zoomed till the straight line is obtained.
