8. PLEASE HELP ME Order the group of quadratic functions from widest to narrowest graph.
y= 6x2, y= -4.5x2, y= -x2

A. y= -4.5x2, y= -x2, y= 6x2

B. y= 6x2, y= -4.5x2, y= -x2

C. y= -x2, y= 6x2, y= -4.5x2

D. y= -x2, y= -4.5x2, y= 6x2

B. y= 6x2, y= -4.5x2, y= -x2

Step-by-step explanation:

y = 6x2, y = −4.5x2, y = −x2

This should be correct )

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}

you would need to know all the numbers that are on there

step-by-step explanation:

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
