This is a problem that I am not sure about. It is difficult to describe because it involves graphs of parabolas that I will
describe as best I can. PROBLEM: Which of the following could be the graph of y=ax +bxsquared + c, where bsquared -4ac=0?
1. Parabola one is negative, turned downward, with vertex high on y axis, not at origin. Two x intercepts 2. Parabola is positive, turned upward, vertex on x axis only, high,upper portion and vertex does not cross y axis. 3 Vertex higher on y axis. Positive, vertex is the origin. 4. Negative, lower than origin, no x intercept. 5. Two x intercepts, positive.
I ruled out 1and 5 because they had 2 x intercepts. I ruled out 4 because it was negative and had no x intercept. I ruled out 3 because its vertex was the origin. Answer is 2. Am I thinking correctly? 0313
