Question

What is the inverse of the function f(x) = 2x + 1?
A.h(x) = 1/2x - 1/2
B.h(x) = 1/2x +1/2
C.h(x) = 1/2x -2
D.h(x) = 1/2x +2

2 Answer

  •       f(x) = 2x + 1
             y = 2x + 1
             x = 2y + 1
        x - 1 = 2y
           2       2
    ¹/₂x - ¹/₂ = y

    The answer is A.
  • Your answser would be A. I just took the test
