Answer: it should be 3 units down

Think if it on a graph in your mind and plot points then use every choice to see which makes sense

For this case we have:

Let k> 0:

To graph
y = f (x) + k, the graph k units is moved up.

To graph
y = f (x) -k, the graph moves k units down.

Let h> 0:

To graph
y = f (x-h), the graph moves h units to the right.

To graph
y = f (x + h), the graph moves h units to the left.

So, we have:


y = f (x) = \sqrt {x}\\h = 3\\y = f (x) = \sqrt {x + 3}

It means that it was shifted 3 units to the left

Answer:

Option A
