Restrict the domain of the function f so that the function is one-to-one and has an inverse function.Then find the inverse function f-1.State the domains and ranges of f and f-1.
F(x) = |x + 5|
A) f-1(x) = x - 5
The domain of f and the range of f-1 are all real numbers x such that x ≥ -5.The domain of f-1 and the range of f are all real numbers x such that x ≥ 0.
B) f-1(x) = x + 5
The domain of f and the range of f-1 are all real numbers x such that x ≥ 0.The domain of f-1 and the range of f are all real numbers x such that x ≥ -5.
C) f-1(x) = x - 5
The domain of f and the range of f-1 are all real numbers x such that x ≥ 0.The domain of f-1 and the range of f are all real numbers x such that x ≥ 5.
D) f-1(x) = x + 5
The domain of f and the range of f-1 are all real numbers x such that x ≥ 5.The domain of f-1 and the range of f are all real numbers x such that x ≥ 0.
E) f-1(x) = x - 5
The domain of f and the range of f-1 are all real numbers x such that x ≥ 5.The domain of f-1 and the range of f are all real numbers x such that x ≥ 0.
