A student claims the graph below represents the solutions to the inequality -4 < x with this graph:
-4
+
-6
-4
+
+
+
+
+
8
-2
0
2
4
6
-8
What was the student's mistake?
The student did x is less than -4, when the variable is on the other side: -4 is less than x so x is greater than -4
The student did not make a mistake; this is the correct graph of the inequality
The student should have multiplied by a negative and switched the direction of the arrow on the graph to go right instead of left
The student should have filled in the point at -4 to show the solution x could be equal to -4
