 Question 45025: given f(x)=3x+4 1.is f(x) a function? why or why not? 2. find f^-1(x) is f^-1(x)a function? why or why not.Answer by Nate(3500)   (Show Source): You can put this solution on YOUR website!given f(x) = 3x + 4 1.is f(x) a function? why or why not? Yes, there are no y-values that result in the same value for 'x'. 2. find f^-1(x) f(x) = 3x + 4 y = 3x + 4 x = 3y + 4 x - 4 = 3y (1/3)x - (4/3) = f^-1(x) Yes, there are no y-values that result in the same value for 'x'.
