# What is the domain of y = 2sinx+ 1?

The domain of the sine function is all Real numbers, or $\left(\setminus \infty , \setminus \infty\right)$.
It might be beneficial to talk about the range of this function. The normal sine function graph oscillates between -1 and 1. Written in interval notation, this would be $\left[- 1 , 1\right]$.
