Algebra 1 - Domain and Range of Linear Functions

This post explains and give practice opportunities related to TEKS A.2A:

determine the domain and range of a linear function in mathematical problems; determine reasonable domain and range values for real-world situations, both continuous and discrete; and represent domain and range using inequalities;

Instruction

Students learn how to find the domain (set of independent [x] values) and the range (set of dependent [y] values) in both continuous (all possible numbers between points) and discrete (whole, concrete numbers found by counting) data sets.

Here are some activities you can use to teach this standard.

STAAR Practice

Between 2016 and 2023 (including redesign practice), this readiness standard has been tested 15 times on the STAAR test. Videos explaining the problems can be found below.
