Försöker att lösa den här uppgiften nu, jag lyckades komma fram till att jag har tre punkter 0, 2 och 5 Först deriverade jag funktionen f (x) = x^4 4x^3 x^2 f´(x) = 4x^3 12x^2 Determining Whether the Inverse Function Is a FunctionGraphically, f −1(x) = −x 1 2 −x would look like graph { (x1)/ (2x) 10, 10, 5, 5} In the graph above, you can see that the x and y values approach the vertical and horizontal asymptotes Since it resembles that of an exponential graph, there is only one y value for an x value Om f(x) = kx m så är f(0) = m Det betyder inte att f(m) = m OM m till exempel är 2 så säger villkoret att f(2) = 6 Om f(x4) f(x) = 2 så betyder det att funktionsvärdet ökar med två då argumentet ökar med 4 Det är alltså ett mått på lutningen Jag föreslår att du försöker rita en linje som stämmer med villkoren
