I am fine.

hi raheem how are you? ok my question is you know in the question they put x>2 right and that means i can chose any values greater than 2 like 3,4,5 and i sub in to equation and get the values and i will get the range values so which value should i use dont i use the one i sub in 3 to the equation cause that is the minimum value?many thanks
The equation is
If we sub in x=3, we get, g(x)=3
If we sub in x=4 we get, g(x)=2
If we sub in x=5 we get, g(x) = 1.66666666666
If we sub in x=100 we get, g(x)=1.020408163
If we sub in x=1000 we get, g(x)=1.002004008
From above we can deduce that no value will be less than or equal to 1.
X=3 is not the minimum value for domain of x>2.
Now sub in x=2.01, we get, g(x)=201
Now sub in x=2.000001, we get, g(x)=2000001
This shows us that the range is g(x)>1.
Do you understand it now?
