Find the intercepts of the graph of the equation

y= x^2 -4
X^2 -9

a. there is no intercept

b. the intercept(s) is/are
type the ordered pair, using intergers or fractions

  • pre-calculus -

    y = p(x)/q(x), a fraction. As with all fractions, it is zero when the numerator is zero. So, there are x-intercepts where x^2-4 = 0 (as long as x^2-9 is not also zero)

    there is a y-intercept where x=0

    that help?

  • pre-calculus -

    yes that does some. I am having to take this for nursing even when we do not use it. I am having a hard time with this course. Thanks alot!!
