What is the range of the function f(x) = 4x  6 when the domain is {3,1,1,3,5}? 

Hi Kelsey, The range of a function is the set of numbers that result from applying the function to the numbers in the domain. To determine the range of your function f(x), substitute the numbers 3, 1, 1, 3 and 5 into the function and see what values you obtain. The set of these values is the range of the function. Penny
