Question

list the intercepts for 3x divided by x^2=9?

Answer 1

Is that \[\frac{3x}{x^2}=9\]?

Answer 2

Whoops sorry I meant x^2+9 forgot to shift

Answer 3

Okay so \[\frac{3x}{x^2+9}\]?

Answer 4

yeah

Answer 5

okay what intercepts are you finding, x and y?

Answer 6

yeah and testing for symmetry

Answer 7

To find the y-intercept we let x=0

y=(3*0)/(0^2+9)
=0/9
=0

To find the x-intercept we let y=0

0=3x/(x^2+9)
0=3x
x=0

Our y-intercept occurs at y=0 and our x-intercept occurs at x=0

Here is a graph of the function http://www.wolframalpha.com/input/?i=y%3D3x%2F%28x^2%2B9%29

Answer 9

awesome I had the y-int right I got stuck on the x-int. Thanks for showing the steps!

Answer 10

no worries :D
