Question

A yard is equal in length to three feet. The function f(x) takes a measurement in yards (as input) and returns a measurement in feet (as output).What number will the function return if the input is 12.2?

Answer 1

since yards is the input, you would multiply the input by 3 to get feet

so the equaton would look something like: f(x) = 3x where x is the input

so when x = 12.2 you would replace x with 12.2 to get:

have f(12.2) = 3(12.2)

12.2 *3 = 36.6 feet
