    Algebra 2 Conic Sections - Parabolas -- PLEASE HELP!

    Write an equation of a conic section with the given characteristics.

    parabola with vertex (1,-2), x-intercept 3, and opens to the right.

    I tried to put the information i knew into the standard form for horizontal parabolas: x=a(y+2)^2+1
    I'm stuck with what the x-intercept means though. Do i plug in the pint (3,0) into the equation and solve for a?
