Question

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

Answer 1

See explanation

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.
