The polynomial is the same in standard form
For this case we have the following functions:
We must find
By definition of composition of functions we have to:
So:
We have different signs subtracted and the sign of the major is placed.
Finally we have to:
ANswer:
Set up a proportion.
(8.75/5)=(x/2)
5x=2*8.75
5x = 17.5
x= 3.5
