a yard is equal in length to three feet the function F(y) takes a measurement in yards (as input) and returns a measurement in feet (as output) if the output is 30 what was the input number

Respuesta :

First let us answer it as if the input is 12. Then the output is 36. F(12)=36 If the input is 13, then the output is 39. F(13)=39 So we know the answer is between 36 and 39 The output of 12.5 is the same as the output of 12 plus the output of .5 F(12.5) =F(12) + F(.5) = 36 + 1.5 =37.5 So the question is really what is the output of .2 F(12.2) = …The same as Y=3X with X being the input.
