Chapter 8.2, Problem 8QR

To determine

To Find: The $x-$ and $y-$ coordinates of all points where the graphs of the given functions intersect

Answer to Problem 8QR

the points of intersections are $(0,0)$ and $(\pi ,0)$

Explanation of Solution

Given information:

Two functions

  $y=x^2-\pi x$ and $y=\sin x$

Calculation:

Two functions

  $y=x^2-\pi x$ and $y=\sin x$

  

According to the graph above

  $y=x^2-\pi x$ and $y=\sin x$ are intersect at the points $(0,0)$ and $(\pi ,0)$

Therefore, the points of intersections are $(0,0)$ and $(\pi ,0)$
