Question

Which is the domain of the function f(x)=5/6[3/5]x?

Answer 1

all real numbers. If x=0, the answer will be -5/6 so x=0 is correct. 

Answer 2

Option 1 that is all real numbers is the domain for the given function.

Explanation:

We have been given the expression:

`(-5)/(6)\cdot [((3)/(5))^x]`

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.
