To summarize this data, assuming that the shortest and the tallest students are respectively 47 and 68 inches tall, the interval notation is written as: This indicates that the heights range from 47 to 68, incl

Interval notation is a simplified form of writing the solution to an inequality or system of inequalities, using the bracket and parenthesis symbols in lieu of the inequality symbols. Intervals with parentheses are called open intervals, meaning the variable cannot have the value of the endpoints. ...
using the bracket and parenthesis symbols in lieu of the inequality symbols. Intervals with parentheses are called open intervals, meaning the variable cannot have the value of the endpoints. For example, the solution 3 < x < 5 is written (3,5) in interval notation, because...
That is, it can teach you how to write an inequality in interval notation, and also how to convert interval notation to inequality notation. It can even deal with compound inequalities! Once you're done here, take one more step in your mathematical journey and discover how to graph ...
Graphing Interval notation The interval notation shows the values of the variable that satisfy the inequalities from smaller to biggest. The interval notation uses brackets {eq}[ ] {/eq} to represents the value is part of the solution. Answer and Explanation: The in...
Write the inequality in interval notation and graph it. x: x greater than or equal to 3. Write the interval notation corresponding to the set notation. {x|x less than -7} Express the solution of x ^3 + 3x ^2 < x + 3, using interval notation. ...

The domain of h is the whole real line except for h=-2 and h=-4...I will leave it to you to express that in interval notation. Please note: Your notation is incorrect...what you really mean is (2x+6)/(x2+6x+8)...and the parentheses are CRITICAL! What you have submitted is...
Solve each of the following inequalities, graph the solution, and name using interval notation. 1) 4x + 3 > 2x – 11 subtract 2x from both sides 2x + 3 > -11 subtract 3 from both sides 2x > -14 divide both sides by 2 x > -7) ...
