Answer 1

(0, - 4 )

Explanation:

Given f(x) = g(x), then

- 2
`√(3x+4)` = - 2
`√(x+4)` ( divide both sides by - 2 )

`√(3x+4)` =
`√(x+4)`

Square both sides

3x + 4 = x + 4 ( subtract x from both sides )

2x + 4 = 4 ( subtract 4 from both sides )

2x = 0 ⇒ x = 0

Substitute x = 0 into either of the 2 functions to find y

g( 0 ) = - 2
`√(0+4)` = - 2
`√(4)` = - 2 × 2 = - 4

Solution is (0, - 4 )
