In this lesson, we will learn how to find the domain and range of a rational function either from its graph or its defining rule.

Q1:

Determine the domain of the function π ( π₯ ) = π₯ + 3 | π₯ β 1 | + 7 2 .

Q2:

For which values of π₯ is the function π ( π₯ ) = π₯ β 2 5 π₯ β 1 2 π₯ + 3 2 2 2 not defined?

Q3:

For which values of π₯ is the function π ( π₯ ) = π₯ β 9 π₯ + 1 1 π₯ + 2 4 2 2 not defined?
