$$\large f(x)=49(\frac{1}{7})^x $$
is this the function for the question? 
or
$$\large f(x)=49(\frac{1}{7})x $$

first one

usukidoll · Answer

ok... well our function doesn't have denominators so there are no restrictions.

usukidoll · Answer

the domain is at the x-axis
the range is at the y-axis

usukidoll · Answer

we need to graph this function t-t
