Hi, I'm trying to create and plot a quadratic function that passes through the point (x,y) (50.8, 120).
If I'm using the general form how would I tweak (presumably) the value of a in order to this?
A quadratic function?
Like in the form y = ax^2 +bx +c ?
That will pass the point (50.8,120)
Tweak the "a" so that the graph will pass through (50.8,120)?
Okay, nothing will stop you from using the quadratic y = ax^2.
You can forget about the bx and c....since they are not specifically called for.
So,
y = ax^2
120 = a(50.8)^2
a = 120 /(50.8)^2
a = 0.0465
That is it.
