Question

How do you write an equation of `y=sinx` with 3 units up?

Answer 1

`y= (sinx) + 3`

Explanation:

The original function is

`y= sinx`

When applying a vertical translation up by `3` units, it is moving the original function up and moving the `y`-intercept up also.

Therefore,

`y= (sinx) + 3`
