precision with which answers can be reported parameter A.CED.2(ES&K) A parameter is a constant or variable term in a function that when changed has an effect on the behavior of the graph of the function but not its general nature. Ability to determine For example, in the intercept form of a line, the parameters are m and b. unknown As the m and b take on different values, the function is still linear, but the graph of each function parameters will differ in slope and/or y-intercept. needed to create an Examples: equation that accurately models a given situation significant digits N.Q.3 (ES&K) Significant digits or significant figures are digits that carry meaning contributing to the Knowledge of precision of the number. and ability to rules of Rules for significant digits significant All non-zero digits are significant digits Example : 22.3 has three significant digits Zeros appearing between non-zero digits are significant Example: 302 has three significant digits Leading are not significant Example: 0.046 had two significant zeros Trailing zeros have several rules that apply Trailing zeros in a number containing a decimal point are significant Example: 7.90 have significant figures Tailing zeros in a number that does not have a decimal point may or may not be significant depending on the context of the problem.
