Question

The domain and range of y = sinx is

• A. R, [0, ∞]
• B. R, [-1, 1]
• C. R, [-∞, ∞]
• D. R, [1, ∞]

Answer 1

Answer: (A), (B)

The correct options are
A

R, [0, ∞]

B

R, [-1, 1]

Sinx is defined for all real numbers, and further for each real number x. So, domain of y = sinx is the set of real numbers and range is the interval [-1, 1].
