Evaluate expressions and intro to relations Name: Use PEMDAS to evaluate each expression below. 1) If 3) If 5) If x 3 , evaluate x 2 6 x x 10 , evaluate 2 x x 10 , evaluate x 2 x 2) If x 2 , evaluate x 2 6 x x 1 x 2 4) If x 16 , evaluate 6) If x 3 x 2 , evaluate 3 x 6 x Instead of evaluating expressions we’re now going to work with equations, but the process is basically the same. Given an input (x), find its partner output (y). All the equations below are called relations since they set up a relationship between one variable (x) and another variable (y). 7) If y 2 x 3 , find the y partner for each x given. a) find y when x = -6 b) find y when x = 0 c) find y when x = 0.5 8) Find 9) Find y when x 3 and y x2 4x y when x 2 and y 7 3x 27 x x 2
