1. Solve for y when x = 1, 2, 3 and 4. 1.) y = x + 9 2.) y = 5x 4 3.) y = 3x Solve for y when x is -2, -1, 0, 1. Patterns and Functions Day 2

2. y = x + 5 x y y = 4x Use the function (rule) at the top of each chart to solve for y for the given values of x. 1.) -2 0 1 2 x y 2.) -2 -4 0 2 4 x y 3.) y = -7x -2 0 1 2

3. x y Write a rule for the function represented by each table 1.) What operation do you use to get y? ___________ Write the rule using variables. _____________ 2.) What operation do you use to get y? ___________ Write the rule using variables. _____________ 3.) Sometimes the rule has more than one operation. What operations do you use to get y? ___________ Write the rule using variables. _____________
