How do you find the y-intercept?

• replace all x-values with 0

• replace all y-values with 0

• set denominator equal to 0

• compare the degrees of the numerator and denominator

How do you find the x-intercept?

• replace all x-values with 0

• replace the y-value with 0 or make the numerator equal 0

• set denominator equal to 0

• compare the degrees of the numerator and denominator
