Is this true because anything above 0 makes the parabola narrow and anything under 0 makes it wider?

anonymous · Answer

yes

1/2 is wider

anonymous · Answer

to make it wider it has to be between 1 and 0

anonymous · Answer

-2 is still narrow

Do you mean

Is this true because |a| above $\large \color{red}{1}$ makes the parabola narrow and anything under $\large \color{red}{1}$   makes it wider?

@ganeshie8  yah thats the one i met :p I kinda screwed up there

cwrw238 · Answer

the coefficient of x^2 is positive so it will be curved up
yes the 2 coefficient of x^2 will make the parabola narrower
