Question

Help please? Please help me with widest to narrowest: y=x^2, y=5x^2, y=3x^2.

Answer 1

Why not graph all of them and see for yourself wich is the widest, etc..

Answer 2

Wait! How do I graph them?

Answer 3

Do you have agraphing calculator?

Answer 4

No.

Answer 5

Did you learn how to graph y = x^2 in class?

Answer 6

No.

Answer 7

How did your teacher assign such a question if you didnt learn how to graph y = x^2 in class beats me.

Answer 8

I don't know either. This is very new to me.

Answer 9

But in any event, if you take a function, say y = x^2 and multiply it by a number greater than 1, say 5, you get 5x^2 which will be narrower than y = x^2. So 5x^2 is the narrowest of the three; 3x^2 will be narrower than x^2. So from the three, 5x^2 is the narrowest, then 3x^2, then x^2.

Answer 10

y = x^2 is a U-shaped parabola

Answer 11

so 5x^2 will also be U-shaped nut narrower than x^2

Answer 12
