Answer:

y= -x^2

vertex: (0, 0)

a= -1

domain: (-∞, ∞)

range: (-∞, 0]

axis of symmetry: y-axis (x = 0)

increasing on: (-∞, 0)

decreasing on: (0, ∞)

y= (x-2)^2-3

vertex: (2, -3)

a = 1

vertical shift: shift of 3 units downwards from the origin

horizontal shift: 2 units to the right

width: 1

reflected? nope

y= (x-1)^2-2

vertex: (1, -2)

a= 1

domain: all real numbers

range: y ≥ -2

axis of symmetry: x = 1

increasing on: (-∞, 1]

decreasing on: [1, ∞)

y = (x+1)^2+2

vertex: (-1, 2)

a = 0

vertical shift: 2 units upwards from the origin

horizontal shift: 1 unit to the left

width: infinite

reflected? no
