What are true of the function f(x)=49(1/7)x? check all that apply

The given function is : y= f(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, , 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 =1 then  = 7,

so ,.

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

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.
