y = a (x + c)² + d

Allgemeine quadratische Funktion: 

y = x²

x \rightarrow a (x + c)² + d 

d = 0 (slider from -10 to 10, step 0.1)
c = 0 (slider from -10 to 10, step 0.1)
a = 1 (slider from -10 to 10, step 0.1)
e_1: 1.0 * 1.0 * 1.0 * 1.0 * 1.0 * 1.0 y = a (1.0 * 1.0 * 1.0 * 1.0 * 1.0 * 1.0 x + c)^(2.0) + d
