Sign charts precalc
WebThe Professor describes how to solve rational inequalities using sign charts. WebSign charts are simply number lines with (pos) or (neg) signs on them to represent whether or not the function’s y-values are positive or negative. For polynomial functions, the critical numbers for the sign chart are the zeros of the function. Example 3: Make a “sign chart” for the function fx x x x()( )( )=- - +13(5)2

Introducing intervals, which are bounded sets of numbers and are very useful when describing domain and range. We can use interval notation to show that a value falls between two endpoints. For example, -3≤x≤2, [-3,2], and {x∈ℝ -3≤x≤2} all mean that x is between -3 and 2 and could be either endpoint.
