Question

With aging body fat increases in muscle mass declines the graph to the right shows the percent body fat in a group of adult women and men as they age from 25 to 75 years age is represented along the X-axis and percent body fat is represented along the Y-axis use interval notation to give the domain and range for the graph of the function for women

Answer 1

Step 1

The domain and range of a function is the set of all possible inputs and outputs of a function respectively. The domain is found along the x-axis, the range on the other hand is found along the y-axis.

Find the domain of the graph of the function of women using interval notation.

`\text{Domain:\lbrack}25,75\rbrack`

Step 2

Find the range of the graph of the function of women using interval notation.

`\text{Range:}\lbrack32,40\rbrack`

Therefore, the domain and range in interval notation for the women respectively are;

`\begin{gathered} \text{Domain:\lbrack}25,75\rbrack \\ \text{Range:}\lbrack32,40\rbrack \end{gathered}`
