How many real and imaginary solutions does the equation x^2-3x=-2x-7 have?

The function ƒ is defined by ƒ(x) = (x + 3)(x + 1). the graph of ƒ in the xy-plane is a parabola. which interval contains the x-coordinate of the vertex of the graph of ƒ?

How can you tell when x and y are not directly proportional?
