Consider the graphs of f(x) = {x} + 1 and g(x) = . The composite functions f(g(x)) and g(f(x)) are not
commutative, based on which observation?
a. The graphs of f(x) and g(x) intersect each other.
b. The graph of g(x) contains negative values.
c. The domains of f(x) and g(x) are different.
d. The y-intercepts of f(x) and g(x) are different.

what are you trying to solve here

step-by-step explanation:

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.
