Question

What is the order , from the narrowest to widest graph , of the quadreatic functions f(x) = -10x2, f(x)=2x2,f(x) =0.5x2

a. f(x) =-10x2,f(x)=2x2,f(x) =0.5x2
b.f(x)=2x2,f(x) =-10x2,f(x) =0.5x2
c.f(x)=05x2,f(x)=2x2,f(x) =-10x2
d.f(x)=0.5x2,f(x)=-10x2,f(x)=2x2
is it D ?

Answer 1

Alright, we do this exactly the same way, with one amendment: We use the absolute value of the numbers in front of x^2

Answer 2

B?

Answer 3

Not B.

|-10| = 10. |2| = 2, |0.5| = 0.5.

The larger the absolute value, the narrower the graph.

Answer 4

My last guess is a?

Answer 5

I really got to look closer when they r all so tight together.

Answer 6

a is correct :)

Answer 7

Ty I learned something today :) I have a lot of issues with math.

Answer 8

My pleasure :)
