Answer:
x is less than or equal to 3
Step-by-step explanation:
The dot is a closed dot, which means that it is something or equal to, and the arrow is pointing down, which means less than. So the sign would be less than or equal to (sorry I don't have that sign on my computer). The dot is on three, so the inequality is x is less than or equal to 3.
<span>When x is 4, </span>
<span>y = 11 (11 =/= 4) </span>
<span>When x is 2, </span>
<span>y = 5 (This is correct) </span>
<span>When x is 4, </span>
<span>y = 11 (11 =/= 3) </span>
<span>When x is 0, </span>
<span>y = -1 (-1 =/= -3)</span>
