Question

Algebra 2 help needed....

Answer 1

Explanation:

We actually don't need to know all of the restrictions.

We know that a vertical stretch factor of 4 means multiplying a square root function by
`4`. So, the answer will be in the form
`y=4√(x+c)+k`, where c and k are real numbers.

Aha! Only one of these conditions satisfy the restrictions, so we have that
`\boxed{y=4√(x+3)+7}` has to be the answer.
