Tell whether the graph opens upward or downward. Then find the axis of symmetry and vertex of the graph of the function.
y=-1/4x^2-24

  • Math; Please Help!o: -

    y=-1/4x^2-24
    Hints:
    If the leading coefficient of a quadratic expression is negative, it opens downwards.
    For a general quadratic equation
    y=ax²+bx+c,
    The axis of symmetry is at the line
    y=-b/2a

    Which one is the B in my equation?

  • Math; Please Help!o: -

    y=ax²+bx+c,
    b is the coefficient of the term in x.
    Since your expression does not have an x-term, b=0.
