Answer:
Option 1 that is all real numbers is the domain for the given function.
Step-by-step explanation:
We have been given the expression:
[tex]\frac{-5}{6}\cdot [(\frac{3}{5})^x][/tex]
Domain is the values that x will take
Here, x can take all the values, negative,positive,fractional any value
Hence, domain of the function is all real numbers.
Therefore, option 1 is correct.
And by the same reasons all the other three option 2,3 and 4 are discarded.
