Answer to Problem 13RE

The domain of f is [3,) .

The range of f is [0,) .

Explanation of Solution

Given information : The function f=x+3 is given.

Formula used : The domain of a function is the set of values that can be taken as x. The range of a function is the set of values that comes as answer to the domain.

Calculation :

To calculate the domain of f, find out the acceptable values of x.

The expression inside root cannot be negative,

  x+30x3

Therefore the domain of f = [3,) .

To calculate the range of f, find out the possible answers of the function.

The function f cannot be negative value hence the range of f = [0,) .
