The function f is one-to-one. State the domain and the range of f and f-1. Write the domain and range in set-builder notation.f(x) = 6x - 2
A. f(x): D = {x|x > 6}, R is all real numbers; f-1(x): D = {x|x < 6}, R is all real numbers B. f(x): D is all real numbers, R = {y|y > -2}; f-1(x): D is all real numbers, R = {y|y < -2} C. f(x): D is all real numbers, R is all real numbers; f-1(x): D is all real numbers, R is all real numbers D. f(x): D = {x|x > 6}, R = {y|y > -2}; f-1(x): D = {x|x < 6}, R = {y|y < -2}
Graph f as a solid line and f-1 as a dashed line in the same rectangular coordinate space. Use interval notation to give the domain and range of f and f-1.f(x) = x2 - 5, x ? 0
A. 
f domain = (-?, ?); range = (-5, ?)
f-1 domain = (-?, ?); range = (5, ?)
B. 
f domain = (0, ?); range = (-5, ?)
f-1 domain = (0, ?); range = (5, ?)
C. 
f domain = (-?, ?); range = (-5, ?)
f-1 domain = (-?, ?); range = (-5, ?)
