Help with 1-7 please

In Exercises 1-4, fill in the blank(s). 1. If f and g are functions such that f(g(x)) = x and g(f(x)) = x, then the function g is the function of f, and is denoted by 2. The domain of f is the of f-1, and the of f-1 is the range of f. 3. The graphs of f and f- are reflections of each other in the line 4. To have an inverse function, a function f must be ; that is, f(a) = f(b) implies a = b 5. How many times can a horizontal line intersect the graph of a function that is one-to-one? 6. Can (1, 4) and (2, 4) be two ordered pairs of a one-to-one function? Procedures and Problem Solving Finding Inverse Functions Informally In Exercises 7-14, Verifying Inverse Functions Alg find the inverse function of f informally. Verify that 19-24, show that f and g f(f-1(x)) = x and f-1(f(x)) = x. algebraically. Use a graphing 7. f(x) = 6x 8. f(x) = 3x in the same viewing window. 10 2 between the graphs
