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

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.
