Solving Inequalities with Interval Notation

Which of the following is the same as the given graph?

• $\left(-\infty,\ -2\right]\cup\left[3,\infty\right)$

Write the following solution in interval notation:

x ≥ -3

• [ -3, ∞ )

Which of the following is the same as the given graph? (check all that apply)

Write the interval notation for the graph?

• [-3, 2)

• -3<x<2

• (-∞, -3] U (2, ∞)
