Domain of the function f(x) = cos x : ( - infinity , + infinity)

Step-by-step explanation:

Let the given function f(x) = cos x

We need to find the domain set of the given function f(x) = cos x

Domain is the set of all possible value of x for which the function f(x) is defined.

Now, as the given function f(x) is defined for all the real values of x.

Domain of the function f(x) = cos x : ( - infinity , + infinity)

Hence, Domain : ( -∞ , +∞ )

Also, the graph of the given function f(x) = cos x is attached below :

Now, form the graph also we can see the graph of given function f(x) = cos x can attain all the real values starting from -infinity to +infinity

80+60+y=180

then divide the difference between 60 and y and add it to 180

so x =180 +( (y-60)/2)

x equals 200
