Question

Help me answer this question please

Answer 1

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

Answer 2

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
