For each equation that has a graph, identify the type of graph. It may be necessary to transform the equation.
Try completing the square. Alternatively, use the quadratic formula to identify the values of y that solve the equation. Note that when y=0, x=-6 so this is a point.
You can also find stationary points and identify whether they are a minima or maxima and then draw a rough graph of the shape of teh function. This will help you identify the type of graph. Love to help further but Ive got a mad assignment to complete
