Question 1090262: What are and HOW would I find the x and y intercepts, domain and range, and graph of y=sinx, -2pi less than or equal to x less than or equal to positive 2pi
I don't have the symbols with the equal to sign included but to verify the equation is : y=sinx, -2pi < x < 2pi

The domain is the possible x values and is specified as ( without qualifications, the domain of "sin(x)" is all real x values, however, some will say this problem is domain restricted to )
The range is all the values y can take on for values of x in its domain. Since y=sin(x) can only take on values between -1 and 1 inclusive, the range is
—
The y intercept is found by setting x=0: y = sin(0) = 0
y intercept is

The x intercept(s) are found by setting y=0: 0 = sin(x)
Where does sin(x) = 0?
At , , , , and
x intercepts are , , , , and
