I will presume you mean -sqrt%28x-3%29%2B7. It's more interesting than -sqrt%28x-3%2B7%29+=+-sqrt%28x%2B4%29

Even (especially?) when writing the expression in words, appropriate use of parentheses is important.

Replacing x with x-3 produces a horizontal shift of +3. (sqrt%28x%29=0 when x=0; sqrt%28x-3%29=0 when x=3).

ANSWER A: Horizontal shift: +3

Replacing the square root with -square root reflects the graph over the x-axis; there is no vertical stretch.

ANSWER B: Reflections: x-axis

The +7 at the end of the expression produces a vertical shift of +7.

ANSWER C: Vertical shift: +7

For stretch/shrink, I will guess you mean horizontally. There is no horizontal stretch or shrink; that would happen if, for example, x were replaced with 3x, or with x/4.

ANSWER D: (horizontal) stretch/shrink: none
