In the function

f(x) = 3x + 9
how does a decrease of 1 in the independent variable x affect
f(x)?

f(x) will have a decrease of 3
f(x) will have a decrease of 12
f(x) will have an increase of 3x + 3
f(x) will have an increase of 3

f(x-1)=3(x-1) +9
3x-3+9
3x+6    f(x)=3x+9  decrease =
                     3x+6
