write the equation of a parabola that opens upward with an axis of symmetry of x=-7/2...
this means that -b/(2a) = -7/2
I can assume that a = 1, b = 7 here.
we would not know c...
f(x) = x^2 + 7x is one possible equation for this parabola.
in general, we can say that the equation for the parabola is g(x) = x^2 + 7x + c for c is any real number.
