Exponential and Logarithmic Relationships
Connect numerical patterns to exponential and logarithmic functions.


Work through official released questions with their original diagrams, answer choices, and griddable responses. TEA's answer keys determine every score. Each tested standard also has a lesson with instruction, a worked example, practice, and videos.
Algebra II and Geometry are not among Texas's five current required STAAR EOC assessments. These official 2013 releases predate the newer online player, so their original multiple-choice and griddable formats are preserved rather than replaced with invented interactive item types.
50 official items · 14 original figures · 5 griddable responses
Practice gives feedback after each item. The full test works like the real one: answers stay hidden until you submit, then you get a score report by topic. Answers are scored from TEA's key. TEKSForge wrote the step-by-step and distractor explanations because this archived release does not include item rationales.
The labels below reproduce the standards and readiness classifications in TEA's 2013 key.
