Syntax Question (89)
I am trying to write a program to generate a Quadratic Equation from a set of
point for the vertex (h,k) and any point on the graph.
I can get the leading coeficient "a" okay. But then I try to pass that on to
generate the full equation. using the formula Y=a(x-h)^2+k
I keep getting snagged on that last setp.
Can anyone shed light on this.
I do have TI-Link and am programing in my computer then sending the file to the
TI89.
Following is one of my many attempts
