Chapter 7: Q8. (page 356)

Graph each polynomial function. Estimate the x-coordinates at which the relative maxima and relative minima occur.

鈥�f(x)=x3+2x2-3x-5

Short Answer

Expert verified

The graph is:

The relative maximum has x-coordinate = -1.869 and the relative minimum has x-coordinate = 0.535.

Step by step solution

01

Step 1. Given

Given that a function is f(x)=x3+2x2-3x-5.

02

Step 2. To determine

We have to graph the function and estimate the x-coordinates at which the relative

maxima and relative minima occur.

03

Step 3. Calculation

We graph the given function using a graphing calculator.

From the graph the relative maximum has x-coordinate = -1.869 and the relative minimum has x-coordinate = 0.535.
