Which graph represents the solution set of and ? graph I
graph II

graph III
graph IV

A.
graph I
B.
graph II
C.
graph III
D.
graph IV

Step-by-step explanation:

Look at the picture.

We have

y = x² - 4 → move the graph of x² 4 units down (the vertex is (0, -4))

x + y + 2 = 0   subtracy x and 2 from both sides

y = -x - 2 → move the graph of -x 2 units down (the y-intercept os -2)

Only graph III and IV meets these conditions.

The solution is the points of intersection of the graphs.

Therefore your answer is GRAPH III
