Question

I need more help!....

Answer 1

1) Factored Form: y = (x - 3)(x + 1)

X intercepts: (-1, 0), (3, 0)

Axis of Symetry: x = 1

Vertex: (1, -4)

Domain: All real numbers - (-∞, ∞)

Range: y ≥ 4

2) Facotred Form: y = (x - 8)(x + 1)

X intercepts: (-1, 0), (8, 0)

Axis of symetry: x = 3.5

Vertex: (3.5, -20.25)

Domain: All real numbers - (-∞, ∞)

Range: y ≥ -20.25
