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

**MathMate**, Thursday, March 1, 2012 at 8:57pmy=ax˛+bx+c,

b is the coefficient of the term in x.

Since your expression does not have an x-term, b=0.
