See explanation

It all depends on how $k$ is incorporated into the parent function.

Assuming it is: $y=sqrt(x)+k$

In this scenario $k=-3$ will lower all the values of $y$ by 3. In other words it 'drops' the graph by 3.

For the parent function y= sqrtxy= sqrtx, what effect does a value of k = -3 have on the graph?
