Chapter 10: Q 66. (page 655)

Graph each function.

f(x)=9-9x2.

Short Answer

Expert verified

The graph of the function is half an ellipse.

Step by step solution

01

Step 1. Given information.

We have given function f(x)=9-9x2.

To obtain equation of ellipse we have

(f(x))2=9-9x2x21+(f(x))29=1

The center of the ellipse lies at the origin and the major axis is y-axis.

02

Step 2. Graph of the function. 

The vertices are at (0,±3).

The x-intercept are at (±1,0).

The graph of the function is given as
