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

Nov 19, 2017

$y = \left(\sin x\right) + 3$

Explanation:

The original function is

$y = \sin x$

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

Therefore,

$y = \left(\sin x\right) + 3$
