Which are true of the function f(x) = 49(1/7)^x check all that apply.

The given function is : y= f(x) =49 [\frac{1}{7}]^x

The statements which are true regarding this function is  

1. As you can observe that y is defined for all values of x , so Domain is set of all values that x can take which is set of all real numbers.

2. Also, x =\frac {\log[\frac{y}{49}]}{-\log7}, so x is defined for all values of y. Range is all values that y can take which is also set of all real numbers greater than zero, i.e y>0.

As ,x =0 then y= 49 and x_{1} =1 then y_{1}  = 7,

so ,y_{1} = \frac{y}{7}.

So, Option (1),(4) and (5) are correct.
