X-INTERCEPTS: Where the graph crosses the x-axis
Hey, this is the same as finding the zeros!
But, here's the cool thing: For these rational guys, you just need to set the numerator = 0 and solve!
Why? That's a great question -- I'm glad you asked...
Well, when a fraction is 0, it's the same as saying the numerator is 0:
So, set the numerator = 0 and solve.
Check it out:
So, the x-intercepts are the points
