Question

Use a graphing calculator to estimate the x-coordinates of the inflection points of the function, rounding your answers to two decimal places. [Hint: Graph the second derivative, either calculating it directly or using NDERIV twice, and see where it crosses the x-axis. Enter your answers as a comma-separated list.]

f(x) = x5 − 7x3 + 6x + 2

Step 1

Given,

Step 2

By calculation, derivative of f(x) are

Step 3

For inflection points, second derivat...
