x and y intercept of y=x^3+7x^2+10x

  • college algebra - ,

    for the x-intercept let y = 0
    x^3 + 7x^2 + 10x = 0
    x(x^2 + 7x + 10) = 0
    x(x+2)(x+5) = 0

    so x = 0, -2, -5
    (your x-intercepts)

    for the y-intercept, let x = 0
    then of course y=0

    so 3 x-intercepts, one y-intercept
