# How do you write and graph a function that translates y=sqrtx by shifting 4 units to the left?

Aug 2, 2018

$\sqrt{x + 4}$

#### Explanation:

Since shifting right or left affects the $x$ values, we add or subtract some value from $x$.

Shifting left corresponds to adding, and shifting right corresponds to subtracting. With this in mind, we get

$\sqrt{x + 4}$

Hope this helps!
