Answer:

Graph B

Step-by-step explanation:

4x + 4 > -20

Subtract 4 from each side.

4x > -24

Divide both sides by 4.

x > -6

So there would be an open circle at -6 with everything shaded to the right.

Graph B give the solution set at negative 6. Option b is correct.

Solution sets are the set of values of the functions.

Here,
4x + 4 > –20
Simplification
⇒ 4x>-20-4
x > -24/4
x > -6

Thus, Graph B has an open circle at negative 6 with everything shaded to the right shows the solution set.
