Question
Which function has a range of {y|y ≤ 5}?
f(x) = (x – 4)2 + 5
f(x) = –(x – 4)2 + 5
f(x) = (x – 5)2 + 4
f(x) = –(x – 5)2 + 4
f(x) = (x – 4)2 + 5
f(x) = –(x – 4)2 + 5
f(x) = (x – 5)2 + 4
f(x) = –(x – 5)2 + 4

f(x) = –(x – 4)^2 + 5
Reason: It's a downward-opening parabola in vertex form with vertex (4, 5), so its maximum value is 5 and the range is {y | y ≤ 5}.
