Question

Order the group of quadratic functions from widest to narrowest graph. y = 6x2, y = −4.5x2, y = −x2

Answer 1

y = 6x2, y = −4.5x2, y = −x2

This should be correct answer:) He got it mixed up in his answer below when graphing.:)

Answer 2

To solve this problem you must keep on mind the following information: By definition, a quadratic function has the following form:

`y=ax^(2)+bx+c`
Where
`a` is the leading coefficient.
If the leading coeficient is closer to zero, the parabola is widest,if it has a larger positive or negative value, the parabola is narrowest.
Therefore, by knowing the information above, you have that the answer is:

`y=- x^(2) \\ y=-4.5 x^(2) \\ y=6 x^(2)`
