X-intercepts of a parabola

  1. Nov 18, 2008 #1
    1. The problem statement, all variables and given/known data
    Identify the x-intercept(s) of the parabola y = (x + 2)2 – 3

    2. Relevant equations

    3. The attempt at a solution
    No idea on where to begin and if I would do the same thing with y

    to find the y intercepts, let x=0,
    so to find the x intercepts let what=0?

    When you have "no idea where to begin" you probably don't understand some of words in the problem. In a case like that it is always a good idea to review the definitions: what do "x-intercept" and "y-intercept" mean?
