Answer:
2, 3 and 6 options
Explanation:
To find the x- intercept, let y = 0 and solve for x, that is
(1)
3x - 6 = 0 ( add 6 to both sides )
3x = 6 ( divide both sides by 3 )
x = 2 ≠ 3
(2)
x - 1 = 0 ( multiply through by 3 )
x - 3 = 0 ( add 3 to both sides )
x = 3 ← x- intercept
(3)
- 2x + 6 = 0 ( subtract 6 from both sides )
- 2x = - 6 ( divide both sides by - 2 )
x = 3 ← x- intercept
(4)
2x = 0
x = 0 ≠ 3
(5)
3x = 3 ( divide both sides by 3 )
x = 1 ≠ 3
(6)
9x = 27 ( divide both sides by 9 )
x = 3 ← x- intercept
