Which function has a domain of x greater-than-or-equal-to 5and a range of y less-than-or-equal-to 3?
y = StartRoot x minus 5 EndRoot + 3
y = StartRoot x + 5 EndRoot minus 3
y = negative StartRoot x minus 5 EndRoot + 3
y = negative StartRoot x + 5 EndRoot minus 3

y = -√(x − 5) + 3
Reason: The radicand x − 5 ≥ 0 gives domain x ≥ 5. For x = 5, y = -0 + 3 = 3; for x > 5 the √(x−5) > 0 so -√(x−5)+3 < 3. Thus the range is y ≤ 3.
