Axis of Symmetry: x = 7, Vertex: (7, -11), Domain: x = ARN → (-∞, ∞), Range: y ≥ -11 → [-11, ∞)

Explanation:

y = x² - 14x + 44

a=1, b=-14, c=44

Axis of Symmetry: x =
(-b)/(2a) =
(-(-14))/(2(1)) =
(14)/(2) = 7

Vertex:

y = x² - 14x + 44

y = (7)² - 14(7) + 44

= 49 - 98 + 44

= -11

x = 7, y = -11
