a) f(x) = - 1/2x + 3 und g(x) = 2x - 3
y-Achsenabschnitte
f(0) = 3
g(0) = -3
Nullstellen / x-Achsenabschnitte
f(x) = - 1/2x + 3 = 0
x = -3/(-1/2) = 6
g(x) = 2x - 3 = 0
x = 3/2 = 1.5
Schnittpunkt der Graphen
f(x) = g(x)
- 1/2x + 3 = 2x - 3
-x + 6 = 4x - 6
5x = 12
x = 2.4
f(2.4) = - 1/2*2.4 + 3 = 1.8
g(2.4) = 2*2.4 - 3 = 1.8
