6-119.

If $g ( x ) = \sqrt { x - 3 } + 1$, find the values below. If there is no solution, justify your conclusion.

1.  $g(7)$

Substitute 7 into the equation.

$g(7) = \sqrt{7 - 3} + 1$

$g(7) = \sqrt{4} + 1$

$g\left(7\right) = 2 + 1$

$g\left(7\right) = 3$

1.  $g(4)$

$g(4) = 2$

1.  $g(8)$

1.  $g(2)$

Can you take the square root of a negative number?
