Ayard 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?

The function will return 36.6 if the input is 12.2.

Step-by-step 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.

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
