Sagot :
Answer:
1.)Given:y=-2x²
Domain: (all real numbers)
Range: {y element R : y>=0} (all non-negative real numbers)
Opening of the parabola: Downward
Vertex: (0,0)
Axis of symmetry: x=0
x-intercept: x = 0
y-intercept: (0, 0)
2.) Given:y=-x²+4
Domain: (all real numbers)
Range: {y/y<=4}
Opening of the parabola: Downward
Vertex: (0, 4)
Axis of symmetry: x = 0
x-intercept: (2, 0), (-2,0)
y-intercept: (0, 4)
3.) Given:y=(x+1)²
Domain: (all real numbers)
Range: {y/y>=0} (all non-negative real numbers)
Opening of the parabola: Upward
Vertex: (-1, 0)
Axis of symmetry: x = -1
x-intercept: (-1, 0)
y-intercept: (0, 1)
4.) Given:y=2x²-4x+4
Domain: (all real numbers)
Range: {y/y>=2}
Opening of the parabola: Upward
Vertex: (-1, -2)
Axis of symmetry: x = 1
x-intercept: None
y-intercept: (0, 4)
