x-intercept: (4, 0)
x-intercept: (-1, 0)
x-intercept: (-5, 0)
x-intercept: (0, 0)
x-intercept: (-3, 0)
x-intercept: (2, 0)
x-intercept: (5, 0)
x-intercept: (1, 0)
x-coordinate of vertex: -0.5
x-coordinate of vertex: 1
x-coordinate of vertex: -1.5
x-coordinate of vertex: 2
x-coordinate of vertex: 3
y = x(x - 2)
y = (x - 4)(x + 5)
y = (x - 1)(x - 5)
y = (x + 3)(x - 7)
y = (x + 2)(x + 1)
