Precalculus, Chapter 1, 1.2, Section 1.2, Problem 22

Determine the intercepts and graph equation y=x29 by plotting points. Be sure to label the intercepts.

x-intercept:


y=x29Given equation0=x29To find the x-intercept, we let y=0x2=9x=±3


The x-intercept is (3,0) and (3,0)

y-intercept:


y=x29Given equationy=029To find the y-intercept, we let x=0y=9


The y-intercept is (0,9)
