Graphing Exponential Functions with Transformations: Reading and Summary
A reading passage and summary practice set for 9th graders on graphing exponential functions, starting from the parent graph f(x) = b^x and applying shifts, stretches, and reflections. It builds skills in identifying y-intercepts, horizontal asymptotes, and growth versus decay, and works well for a single 45-minute math block or small-group review.

Teacher Guide & Tips
- Use this after students have seen the basic shape of y = 2^x and y = (1/2)^x, so the passage can focus on transformations rather than introducing the concept from scratch.
- Discussion question: Why does an exponential graph bend instead of rising by a constant amount, and how does that differ from a linear graph?
- Scaffold for struggling readers: Have them sketch the parent graph first and label the y-intercept and asymptote before reading the transformation section, then compare with the passage.
- Extension for advanced students: Ask them to write a transformed function, such as g(x) = 3·2^(x−1) + 4, predict its asymptote and intercept without a calculator, and then verify by graphing.
- Estimated time: about 40 to 45 minutes for the reading, questions, and a short graphing check.
