Precalculus Worksheet 1. Complete the following questions from your textbook: p11: #5 10 2. Why would you never write 5 < x > 7 ? 3. Why would you never write 3 > x > 8 ? 4. Describe the graphs below using both inequalities and interval notation. Later in the course we will be using sign charts. Sign charts are simply number lines with + or signs on them to represent whether or not the function or equation is positive or negative on that interval. Suppose the sign chart below represents when the function f (x) is positive or negative. Use the sign chart to answer the questions 5 and 6 in interval notation. 5. When is f (x) < 0 ? 6. If f (x) = 0 when x = 2, but not when x = 7, when is f (x) > 0 ? 7. Use both inequality AND interval notation to describe the set of numbers. Define any variables used. a) In Excel, you can create an if-then statement that will enter a specific value or text into a box depending on given conditions.
