Function Problem.?

Question

Hey, I'm stuck on some easy function questions because I don't know what form to put my answers in. Please solve.
Find the domain, range, and zeros of the following functions.

4 p(x) = sin x

6. r(x) = 2/x
thank you

Answer 1

p(x) = sin x
Domain is all the real numbers for x.
Range is -1=< p(x) =< 1
The zeroes occur at 0 and pi and multiples thereof.

r(x) = 2/x
Domain = all real numbers except 0 for x
Range is - infinity There are no x-intercepts
