Which is f ^-1(x)?

• f ^-1(x) = 5x + 3

• f ^-1(x) = 5x - 3

• f ^-1(x) = 5x - 15

• f ^-1(x) = 1/5(x) + 3/5

Find the inverse of f(x) = -3x + 3

• f^-1(x) = -3x + 1

• f^-1(x) = -1/3x + 1

• f^-1(x) = -1/3x - 1

• f^-1(x) = 1/3x + 1

Find the inverse function

• f ^-1(x) =(1/x) − 5

• f ^-1(x) =(1/x) + 5

• f ^-1(x) = (x/1) − 5

• f ^-1(x) =(5/x) − 1
