Presentation transcript:

Section 1.3.1 – Linear Inequalities (NC) [All answers written in interval notation] Given the 12 examples on the next slide, discuss the following within your group. You have four minutes: When do you use parenthesis? ( ) When do you use brackets? [ ] When do you use Which of the 12 examples is INCORRECT?

Inequality Interval Notation

Based upon your findings on the previous slide, write each inequality using interval notation. Unbounded Bounded How do you know if an equality is bounded or unbounded? Inequality Interval Notation

Find all integers which satisfy -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5 Solve for x, writing your answer using interval notation. (-6, 6) Solve for x, writing your answer using interval notation. (3, 9)

Ellipsis Find all integers which satisfy …-10, -9, -8, -7 7, 8, 9, 10, … Solve for x, writing your answer using interval notation. Solve for x, writing your answer using interval notation.
