Question

let f(x)=0.5x^3-4x^2-2x+5.a.use n deriv to graph f(x),f'(x),f"(X)on the window xmin = -5,xmax=10,ymin= -50,ymax= 10

Answer 1

We can't draw graphs here. It is just a matter of calculating and plotting the (x,y) numbers from x=-5 to x = +10

I assume you know how to take the derivatives that are requested.
In this case,
f'(x) = 3x^2 -8x -2
f"(x) = 6x - 8

They want you to plot those curves also. The last one is a straight line.

Answer 2

What is youor question? How to graph them?
