Tell whether the graph opens upward or downward. Then find the axis of symmetry and vertex of the graph of the function.
If the leading coefficient of a quadratic expression is negative, it opens downwards.
For a general quadratic equation
The axis of symmetry is at the line
Which one is the B in my equation?
b is the coefficient of the term in x.
Since your expression does not have an x-term, b=0.
