Hello.

I have an equation which I understand partially but after understanding the purpose of coefficients in the below equation I think my understanding will enhance.

* I found it on: https://www.desmos.com/calculator/dnzfajfpym

What decides that I need coefficients for x

I think that coefficients of x

But how do I come up a number that is so precise like:

which is the coefficient of x

Do I need to solve a few equations to come up with the coefficient of x

Thanks!

^{2}in the given equation of this post?I think that coefficients of x

^{2}in this post's equation exist to scale up or scale down the size of the thing drawn in blue box: Correct?But how do I come up a number that is so precise like:

which is the coefficient of x

^{2}to complete the sketching of the curve (Batman)?Do I need to solve a few equations to come up with the coefficient of x

^{2}in the following equation?Thanks!
