Question

What are the domain and range or this exponential function y= 2(1/9) x-5 -4

Answer 1

Given:

`y=2((1)/(9))^(x-5)-4`

Here, domain set of x values at whcih the function is defined

So, x can take any values from all real numbers

Hence, the domain of the given function is real numbers.

`\text{Domain}=(-\infty,\text{ }\infty)`

The range can be found out as,

The maximum value of an exponential function approches to infinity when x is equal infinity and the minimum value of an exponential function approches to
