Updated: Sep 2

This post explains and give practice opportunities related to TEKS A.9B:

interpret the meaning of the values of a and b in exponential functions of the form f(x) = abx in real-world problems


Students interpret real-world situations involving exponential functions, applying their knowledge to identify the initial amount (principal) and the rate of change.


STAAR Practice

Between 2016 and 2023 (including redesign practice), this supporting standard has been tested 6 times on the STAAR test. Videos explaining the problems can be found below.
