Answer: x= -(1/2)

Step-by-step explanation:

(x+5 +3) / x+3 = 3

Multiply both sides by (x+3)

(x+8)= 3(x+3)

x+8 = 3x+9

-2x = 1

x= -1/2

CHECK:

-1/2 +8 = 15/2 -1/2+3 =5/2

15/2 : 5/2 = 15/2*(2/5) = 30/10 = 3

Consider the function represented by the graph.

Brut [27]

It looks like A {x|x > or = 0}.
But, your picture is blurry so it’s hard to see. If it’s a solid dot on the top left of the line and an arrow at the bottom right, then A is the correct answer. If that’s not what those are, sorry.
