Question

What are the domain and range of y = sin x? Select one choice for domainand one for range.A. Range: All real numbersB. Domain: 2 + 3 + nnC. Domain: All real numbersD. Range: -1

Answer 1

C. Domain: All real numbers

D. Range: -1

Explanation:

The domain is the range of input values in a function (values on the x-axis) and the range is the range of output values of a function (values on the y-axis).

Therefore, in the function y = sin x:

`\begin{gathered} D=(\infty,\infty) \\ R=\lbrack-1,1\rbrack \end{gathered}`
