Question

Describe the domain and range of y=secx.

Answer 1

Function

Domain is the set of all x values, those makes the function mathematically correct.

So, here the denominator shouldn't be zero i.e .

Since when

So, the domain of the function is all real numbers except where n is an odd number.

Now graph the function .

 

Range is the values of the function for the corresponding x values.

From the graph we can find range of the function that is

 

Domain : All real numbers except where n is an odd number

Range   :
