Auswirkung von a und b in

f(x)=a \cdot b^x

a = 50 (slider from -5 to 100, step 1)
b = 1.12 (slider from 0 to 5, step 0.01)
f(x) = (a * b^(x))
A = Intersect(f, yAxis, (0, 50))
B = Intersect(xAxis, yAxis)
a_2 = Segment(A, B)
C = Point(xAxis)
D = Point(f)
c = Segment(D, C)
Text1: "f(x) = " + a + "\cdot" + "(" + b + ")" + "^x"
E = Point(f)
