Unit G Summary Question #8: How do you find the y-intercept of a rational function? Does this need to be done in the original or simplified equation?

Mrs. Kirch: "y-intercept!!!"

Students: "x=0 !!!"

To find the y-intercept of a rational function, you must use the simplified equation! So take your simplified equaton and plug in zero for all of the x's you see.
*A y-intercept cannot have more than one intercept. Only one or none.
