Question

the graph of a function f is the segment from (2, 3) to (8, 9), including the endpoints. what is the domain of f?

Answer 1

`2 \leq x \leq 8` or [2, 8]

Explanation:

The domain of a function is the x values for which a function is defined.

In our case, the function is defined between the points (2, 3) and (8, 9), meaning between x = 2 and x = 8.

The points are included in the domain, therefore we can write the domain in two ways:

1. As an inequality:
`2 \leq x \leq 8`

2. Using interval notation: [2, 8]
