Question

A yard is equal to in length of 3 feet. The function F(y) 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

12.2*3
36.6
you are very welcome

Answer 2

The function will return 36.6 if the input is 12.2.

Explanation:

Given,

1 yard = 3 feet,

Let y represents the number of yards ( input ) and f(y) represents the number of feet ( output ) for y yards,

y yards = 3y feet,

⇒ f(y) = 3y,

For y = 12.2,

f(12.2) = 3 × 12.2 = 36.6

Hence, the function will return 36.6 if the input is 12.2.
