Question

Can someone tell me how to find the the widest parabola function from a list?

Answer 1

Are you given a list of functions or equations?

Answer 2

Yea, y=3x^2, y=2x^2

Answer 3

In general, y = ax^2 + bx + c the leading coefficient 'a' determines how wide or narrow the parabola is

Answer 4

the further 'a' is away from 0, the more narrow it gets

Answer 5

as 'a' gets closer to 0, then it gets wider

Answer 6

So the higher the absolute value, the more narrower it gets?

Answer 7

exactly

Answer 8

Ok, thanks very much

Answer 9

you're welcome
