Answer 2

Answer:

Other possible Range of function y = cos⁻¹x is [ -π , 0 ] and [ π , 2π ] .

Step-by-step explanation:

• Let, R be a relation from set A to set B, then set of all first components or coordinates of the ordered pairs belonging to R is called the domain of R, while the set of all second components or co-ordinate of the ordered belonging to R is called the range of R.
• The Domain of function y = cos⁻¹x is [ -1 , 1 ].
• The principal value branch (Range) of function y = cos⁻¹x is [ 0 , π ] .
• Other possible Range of function y = cos⁻¹x is [ -π , 0 ] and [ π , 2π ].
