Which of the quadratics has a graph with x-intercepts of 5 and -1?

a) y = x2 - 4x - 5
b) y = x2 - 5x - 4
c) y = x2 + 4x - 5
d) y = 2x2 - 4x - 5

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

24+x=y
