Given f(x)=cos c and g(x)=cot x, what are the domain and range of f(g(

answer choices:

a. domain: all real numbers; range: all real numbers.

b. domain: all real numbers x except x does not equal npi for all integers n; range: all real numbers.

c. domain: all real numbers x except x does not equal npi for all integers n; range: -1 is less than or equal to y is less than or equal to 1.

d. domain: all real numbers; range: -1 is less than or equal to y is less than or equal to 1.

Alternative C is the correct answer

Step-by-step explanation:

The first step is to determine the composite function;

We then employ a graphing utility to determine the range and the domain of the new function.

The range is the set of y-values for which the function is defined. In this case it is;

On the other hand, the domain refers to the set of the x-values for which the function is real and defined. In this case; it is the set of real numbers x except x does not equal npi for all integers n.
