Question

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

Answer 1

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 2

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)
