What is the domain and range of f(x) = (2/3)^x

Domain = { all real values of x }

Range = { y > 0 }

Step-by-step explanation:

Any exponential function of the form:

Where a is positive

But when a is negative

So, we can see the function is the form where a is positive, hence

Domain = { all real values of x }

Range = { y > 0 }

Note: Graph of this function is shown in attached pic

3

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3
