Can someone please answer this, ill give you brainliest Would be very appreciated.

Answer:

  1. (4, 0) and (-2, 0)
  2. (1, -9)
  3. (0, -8)

Step-by-step explanation:

Finding the x-intercepts :

  • y-value of the x-intercept is 0
  • 0 = (x - 4)(x + 2)
  • x - 4 = 0 ⇒ x = 4
  • x + 2 = 0 ⇒ x = -2
  • The x-intercepts are : (4, 0) and (-2, 0)

Finding the vertex :

  • Expanding the function f
  • f(x) = (x - 4)(x + 2)
  • f(x) = x² - 4x + 2x - 8
  • f(x) = x² - 2x - 8
  • Vertex = (h, k)
  • h = -b/2a = -(-2)/2(1) = 1
  • k = (1)² - 2(1) - 8
  • k = 1 - 2 - 8 = -9
  • The vertex is : (1, -9)

Finding the y-intercept :

  • Substitute x = 0 in the function
  • f(0) = 0² - 2(0) - 8
  • f(0) = -8
  • The y-intercept is : (0, -8)
