Question

If |m| > |n|, then the graph of y=mx^2 is _______ narrower than y=nx^2.

Always, Sometimes, or neither?

I think never, because if it's greater than the other one, it would be wider, not narrower. Anyway please tell me your reasoning.

Answer 1

Always, Sometimes, Never.

Answer 2

Well, when m is negative, it can be "greater" than n. So, mx^2 can be greater than nx^2. So, it can be narrower than nx^2.

Answer 8

The only thing the negative has to do with it is to tell you whether the parabola is concave upward or downward.
