  1. A function is a mathematical formula where the x contained in brackets represents the number you are given (input) and the equation that you write after the equals sign is what you do with x. For example; f (x) = x+2 in this function if x represents 1 then the equation is 1 +2

  2. answer a is 4 answer b is 17 answer c is 0. I found this one difficult because I did not know what the carat symbol ^ represents. It represents exponentiation (the power of)
