# Transformations of functions: Vertical translations

### Transformations of functions: Vertical translations

Vertical translations refer to movements of a graph of a function vertically along the y-axis by changing the y values. So, if y = f(x), then y = (x) + h results in a horizontal shift. If h > 0, then the graph shifts h units up; while If h < 0, then the graph shifts h units down.
