Homework Help: How do you find where x+1 and 9-(x^2) intercept?

  1. Jan 20, 2010 #1
    1. The problem statement, all variables and given/known data

    Find at what points these two functions intercept.

    y=x+1 y=9-(x^2)

    2. Relevant equations

    x+1=9-(x^2)

    3. The attempt at a solution

    (x^2)-x-8=0

    I assume you mean "intersect". Either complete the square or use the quadratic formula. And check the sign on your x term.
