If I change 330 to 300 and 167 to 170 what is the difference between the resulting numbers.

The difference between 330 and 300 is 30, while the difference between 167 and 170 is 3.

Step-by-step explanation:

This is because 330 minus 300 equals to 30 which is the distance between both numbers.  This goes the same with 170-167=3

step-by-step explanation:

f(gx)=f(1/x+2)

=(1/x+2)+2

=(1+2x)/2+2

=(1+2x+4)/2

= (2x+5)/2
