Question

Order the group of quadratic functions from widest to narrowest graph.
3. y=2x^2, y=4x^2, y=5x^2

a. y=5x^2, y=4x^2, y=2x^2
b. y=4x^2, y=2x^2, y=5x^2
c. y=2x^2, y=4x^2, y=5x^2
d. y=2x^2, y=5x^2, y=4x^2

Answer 1

@CJDOG

Answer 2

the larger the coefficient of x^2 the steeper the graph is and closer to the y axis
meaning it is narrower

Answer 3

So A? @amorfide

Answer 4

1. x^2, 3x^2, 5x^2
2. 1/2x^2,-x^2,-8x^2
3. 2x^2,-4x^2,5x^2
4.6x^2,-7x^2,4x^2

The larger the absolute value of the coefficient, the more narrow the graph

Answer 5

sorry dont know

Answer 6

It is A.

Answer 7

Thank you @Ilovecake can you hep me with more?

Answer 8

Yeah. Sure. :)
