Question

If the value of a<0, how does that effect the graph of the parabola when compared to the graph of its parent function?A. It makes the parabola open upward instead of downward.B. It has no effect on the graph.C. It stretches the graph so that it is taller then the graph of its parent functionD. It compresses the graph so that it is shorter then the graph of its parent function

Answer 1

It is important to know that the parent function of a parabola opens upside, in other words, a>0.

However, in this case, the parabola opens downward, given that a<0.

Additionally, if a<0, the parabola will be taller or vertically stretched.

Hence, the answer is C.
