A graph of g(x) is a parabola with a minimum at (-6,-6)
A graph of g(x) - c is a parabola with a minimum at (-6,-6-c)
The interesting thing about this is g(x)-c has two roots, one less than -6 and the other greater than -6. But if c is less than -6 the roots are imaginary.
So if we work backwards we only need the + of the ħin the quadratic formula.
So here is what I did on my calculator:
