2 Vocabulary Function Function Rule A relationship that assigns exactly one output value to each input valueFunction RuleThe operation(s) performed on the input value
3 Vocabulary Domain Range The input values of a function (x values) The corresponding output values (y values)
4 Graphing Functions Step 1 Step 2 Step 3 Step 4 Step 5 Create a table for your function.Step 2Choose at least 3 input values for x. (-, 0, + when possible)Step 3Evaluate the function for each input value.Step 4Plot the points as ordered pairs.Step 5Join the points to form a line.
7 Graph the Function t (x,y) Michael Phelps swims the 400-meter individual medley at an average speed of 100 meters per minute. The equation d = 100t describes the distance d that he can swim in t minutes at this speed. Represent the function by a graph.td = 100t(x,y)
8 Graph the Function c (x,y) You buy a DVD for $14 and CDs for $9 each. The equation t = c represents the total amount t that you spend if you buy 1 DVD and c CDs. Represent this function by a graph.ct = c(x,y)
