Question

What is the domain and range of the function

Answer 1

Option d is correct.

Domain = all real number

range = positive real numbers

Explanation:

Given the function:
`y=f(x) = a^x`

Domain of the function is all real numbers except where the expression is undefined.

In this case, there is no real number that makes the expression undefined.

Domain of f(x) =
`(-\infty , \infty)` = a∈R

Range is the set of all valid f(x) values.

`(0,1) \cup (1, \infty)`

`\y`

Therefore, Domain is all real number and the range of function is positive real number
