Answer:

x-intercept: (4, 0), (-5, 0)

y-intercept: (0, -20)

Explanation:

  • x² + x - 20
  • x² + 5x -4x -20
  • x(x+ 5) -4(x +5)
  • (x-4)(x + 5)

Their x-intercept:    (at x intercept, y will be 0)

  • (x-4)(x + 5) = 0
  • x = 4, x = -5

Their y intercept:   (at y intercept, x will be 0)

  • y = (x-4)(x + 5)
  • y = (0-4)(0 + 5)
  • y = -20

Answer:

  • x-intercepts : (4, 0) and (-5, 0)
  • y-intercept : (0, -20)

Step-by-step explanation:

Finding x-intercept(s)

  • The x-intercept's y-coordinate will be 0
  • ⇒ 0 = (x - 4)(x + 5)
  • ⇒ x = 4 and x = -5
  • The x-intercepts are : (4, 0) and (-5, 0)

Finding y-intercept

  • The y-intercept's x-coordinate will be 0
  • ⇒ y = 0² + 0 - 20
  • ⇒ y = -20
  • The y-intercept will be (0, -20)
