Ayard is equal in length to 3 feet. the function f(x) takes a measurement in yards (as inputs) and return a measurement in feet (as output). what number will the function return if the input is 12.2?

12.2 *3 = 36.6 feet

Step-by-step explanation:

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)

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

hope this is what you were asking for!
