Axis of Symmetry: x = 7, Vertex: (7, -11), Domain: x = ARN → (-∞, ∞), Range: y ≥ -11 → [-11, ∞)
Step-by-step explanation:
y = x² - 14x + 44
a=1, b=-14, c=44
Axis of Symmetry: x = [tex]\frac{-b}{2a}[/tex] = [tex]\frac{-(-14)}{2(1)}[/tex] = [tex]\frac{14}{2}[/tex] = 7
Vertex:
y = x² - 14x + 44
y = (7)² - 14(7) + 44
= 49 - 98 + 44
= -11
x = 7, y = -11
