Part 1
The inverse is f Superscript negative 1 Baseline left parenthesis x right parenthesisequals
y = x^2 - 6
Domain of f: All real numbers greater than or equal to -6
Range of f: All real numbers greater than or equal to 0
Domain of f^-1: All real numbers greater than or equal to 0
Range of f^-1: All real numbers
Since the inverse is a function, the function f(x) is one-to-one.
