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
The number will the function return if the input is 12.2 is 36.6 feet and this can be determined by using the unitary method.
Given :
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).
The following steps can be used in order to determine the function:
Step 1 - The unitary method can be used in order to determine the function.
Step 2 - According to the given data, one yard is equal to 3 feet.
Step 3 - If one yard is equal to 3 feet then 12.2 yards is equal to:
[tex]\rm f(x) = \dfrac{12.2\times 3}{1}[/tex]
Step 4 - SImplify the above expression.
f(x) = 36.6 feet
