quadratic equations
A quadratic equation has the form y = ax^2 + bx + c. However, if c = 0, then y = ax^2 + bx. Is it still called a quadratic equation? And if b = 0 so that y = ax^2, is it still given the title of quadratic equation?
I would guess yes since it still has a power of 2 and is a parabola. Is this correct?
