A student claims that graph below represents the solutions to the inequality: −4<x
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 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
The student's mistake is that they incorrectly represented the inequality −4<x as x<-4, when it should be -4<x. Therefore, the correct statement is: 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 correct answer is:
The student did not make a mistake; this is the correct graph of the inequality
