Answer:

  1. (√30 - 1, 0)
  2. (-√30 - 1, 0)

Step-by-step explanation:

Making the equation of the parabola :

⇒ y = a(x - h)² + k

⇒ y = (x + 1)² - 17 - 13

⇒ y = (x + 1)² - 30

x-intercepts have y = 0 :

  • 0 = (x + 1)² - 30
  • (x + 1)² = 30

Taking the square root on each side :

  • √(x + 1)² = √30
  • x + 1 = ±√30
  • x = ±√30 - 1

The x-intercepts are :

  1. (√30 - 1, 0)
  2. (-√30 - 1, 0)
