Determine whether the parabola y = −x^2 + 15x + 8 opens up, down, left, or right.

OpenStudy (unklerhaukus):

well the important parts of the equation for this question are are \[y=-x^2\]

OpenStudy (anonymous):

ah. So that would mean it would go down correct?

OpenStudy (unklerhaukus):

yeah

OpenStudy (anonymous):

Thanks

If the x is squared it opens up or down, y is squared it opens left of right. If the coefficient of the squared term is positive it opens up or right, negative it opens down or left.
