Evaluate the function when x = 2  {HINT: Should you substitute into the top equation or the bottom equation?}

• f(2) = 2(2) - 5 = 1
• f(2) = 2(2) - 5 = -1
• f(2) = ½(2) + 1 = 2
• f(2) = 4

Evaluate the function when x = 4  {HINT: Should you substitute into the top equation or the bottom equation?}

• f(4) = 2(4) - 5 = 3
• f(4) = 2(4) - 5 = -1
• f(4) = ½(4) + 1 = 3
• f(4) = 4
