Graph the following functions in Desmos (press enter to add a new function)

y = x2 - 2x - 8

y = x2 - 2x - 3

y = x2 + 2x - 15

y = x2 - 2x - 15

Match the characteristics to the functions. Each function should have an intercept form equation, solutions, y-intercept, axis of symmetry, vertex, and range.

  • Solutions: x = -3, x = 5

  • y-intercept: (0, -3)

  • Range: y ≥ -4

  • Axis of Symmetry: x = 1

  • Solutions: x = 3, x = -5

  • Axis of Symmetry: x = -1

  • y-intercept: (0, -8)

  • Solutions: x = 4, x = -2

  • y-intercept: (0, -15)

  • y = (x - 3)(x + 5)

  • Range: y ≥ -9

  • y = (x - 3)(x + 1)

  • y = (x + 3)(x - 5)

  • Vertex: (-1, -16)

  • Vertex: (1, -16)

  • y = (x - 4)(x + 2)

  • Vertex: (1, -9)

  • Solutions: x = 3, x = -1

  • Vertex: (1, -4)

  • Range: y ≥ -16

  • y = x2 - 2x - 8

  • y = x2 - 2x - 3

  • y = x2 + 2x - 15

  • y = x2 - 2x - 15

Sort the functions according to their end behaviors

  • y = (x + 3)(x - 4)

  • y = 2.6x2 + 9x - 4

  • y = -10x2 + 7x - 8

  • y = -x2

  • y = -(x + 3)(x - 4)

  • y = 2x2 -4x + 12

  • y = -3x2 + 6x - 9

  • y = x2

  • as x → ∞, f(x) → ∞;

    as x → -∞, f(x) → ∞

  • as x → ∞, f(x) → -∞;

    as x → -∞, f(x) → -∞
