Question

Which is the domain of the function f(x) = -5/6(3/5)^x

all real numbers
all real numbers less than 0
all real numbers greater than 0
all real numbers less than or equal to 0

Answer 1

The answer is A

Explanation:

all real numbers

Answer 2

Domain of given function f(x) is all real number.

A is correct.

Explanation:

We are given an exponential function.

`f(x)=-(5)/(6)\cdot\left ((3)/(5)\right)^x`

Domain is a input value of x where function is defined. It is exponential function defined everywhere. Therefore, Domain of exponential function is all real number.

Domain in interval form:

`x\epsilon (-\infty,\infty)`

Thus, Domain of given function f(x) is all real number.
