Question
Use your computer or graphing calculator to graph the function and its derivative on the same screen. Verify that the function increases on intervals where the derivative is positive and decreases on intervals where the derivative is negative.$y=x^{3}+2 x^{2}-x-2$
Step 1
The derivative of y with respect to x is given by: y' = d/dx (x^3 + 2x^2 - x - 2) Using the power rule and sum/difference rule, we get: y' = 3x^2 + 4x - 1 Show more…
