What is the domain of f(x)=cos(x)?
what is the y value of tan(x) when x=-180
the range of f(x)=sin(x)is−1≤y≤1

soo sorry about all the questions i really don't understand this section

Range of f(x)=sin(x) is−1≤y≤1

Step-by-step explanation:

Given the function f(x)=cos(x)

we have to find the domain of function f(x)=cosx.

The domain of a function is the complete set of possible values of the independent variable. Here, cosx is defined at all the values of x therefore,

Now, we have to find the y value of tan(x) when x=-180

The range of a function is the complete set of all the possible resulting values i.e all y-values.

Range of f(x)=sin(x) is−1≤y≤1

answer: i believe it’s 245.04

step-by-step explanation:

you probably already have the answer but anyways it's b. 15.0
