The maximum value of y=√ (x+2) - 1 on the interval [-2,2]

1

Step-by-step explanation:

The square root function is monotonically increasing, so will have a maximum at the right end of any interval. Here the maximum is at x=2. That value is ...

y = √ (2+2) - 1 = 2 - 1 = 1

The maximum value on the interval is 1.
