  1. -2 -1 0 1 2 3 4 5 6 7 Starter List the elements in the domain of f List the elements in the range of f List the ordered pairs that describe the relation f Is f a function? What is the equation of the relation? { -2, -1, 0, 1, 2 } { 3, 4,7 } { (-2, 7), (-1, 4), (0, 3), (1, 4), (2, 7) } Yes. All of the first elements are different. y = x2 + 3

  2. Note 5: Linear Functions A linear function is a function of the form f(x) = ax + b where a and b are constants

  3. Joined hexagons are made with matchsticks Complete the table. Find the rule for the number of matchsticks m, needed for the number of hexagons n. How many matchsticks are needed to make 12 hexagons? If we use 126 matchsticks, how many hexagons are there? m = 5n + __ Common difference 5 m = 5n + 1 m = 5 x 12 + 1 = 61 126 = 5n + 1 125 = 5n n = 25 Example
