DO NOW Translate the following algebra statement into English: f(x) = x + 2 2. What does this mean?

Discussion/Practice Read the following math statement in English: f(x) = 2 + x f(x) = 3 + x f(x) = 5x f(x) = x/2 f(x) = 3x – 25

Another Example f(x) = 3x + 25 f(x) = y y = (3 times x) + 25 x = 3 y = ? y = 3(x) + 25 = 3(3) + 25 = 9 + 25 = 34 x = 4 y = ? Y = 3(x) + 25 = 3(4) + 25 = 12 + 25 = 37

Example of Completed Function Table with Calculations Shown f(x) = 4 – x X = 4- x X y Calculations -1 5 4 – (-1) = 4 +1 = 5 4 4 – 0 = 4 1 3 4 – 1 = 3 2 4 – 2 = 2 4 – 3 = 1
