Chapter 8.2, Problem 10QR

To determine

Find the x- and y-coordinates of all points where the graphs of the given function intersect. If the curves never intersect, write “NI”.

Answer to Problem 10QR

The points of intersection are $\left(-0.93,-0.80\right),\left(0.93,0.80\right)\text{and}\left(0,0\right)$

Explanation of Solution

Given information:

The given functions are $y=\sin x\text{ and }y=x^3$

Calculation :

To obtain the points of intersection graph the functions.

  

Therefore,

The points of intersection are $\left(-0.93,-0.80\right),\left(0.93,0.80\right)\text{and}\left(0,0\right)$
