Looking for exponential functions worksheets for Algebra I? This page has 1,113+ TEKS-aligned practice questions on this exact topic. Every question goes through an AI quality gate before publishing — no typos, no wrong answer keys, no factually-broken explanations.
Below: a sample of 8 questions with answers and explanations so you can see what's on the worksheet before you print. Each question has the correct choice marked and a one-line "why" so kids who get it wrong understand the fix.
Evaluate f(3) for f(x) = 1 · 5^x.
- 126
- 125 ✓
- 127
- 124
Why: f(3) = 1 · 5^3 = 1 · 125 = 125.
Is f(x) = 643 · (1.15)^x exponential growth or decay?
- Neither
- Linear
- Decay
- Growth ✓
Why: Since the base 1.15 > 1, the function shows exponential growth.
Is f(x) = 953 · (0.81)^x exponential growth or decay?
- Neither
- Decay ✓
- Growth
- Linear
Why: Since the base 0.81 < 1, the function shows exponential decay.
Is f(x) = 615 · (0.78)^x exponential growth or decay?
- Neither
- Decay ✓
- Growth
- Linear
Why: Since the base 0.78 < 1, the function shows exponential decay.
Is f(x) = 176 · (0.89)^x exponential growth or decay?
- Decay ✓
- Growth
- Neither
- Linear
Why: Since the base 0.89 < 1, the function shows exponential decay.
Is f(x) = 114 · (0.89)^x exponential growth or decay?
- Growth
- Linear
- Neither
- Decay ✓
Why: Since the base 0.89 < 1, the function shows exponential decay.
Is f(x) = 867 · (1.29)^x exponential growth or decay?
- Growth ✓
- Neither
- Linear
- Decay
Why: Since the base 1.29 > 1, the function shows exponential growth.
Is f(x) = 388 · (1.24)^x exponential growth or decay?
- Growth ✓
- Linear
- Neither
- Decay
Why: Since the base 1.24 > 1, the function shows exponential growth.
Common questions
Are these worksheets really free?
Yes. Free to print, free to practice online. No email, no sign-up, no paywall. We make money from optional paid features (toy redemption with real cents), not from the worksheets.
What TEKS standards does this cover?
This unit aligns to multiple Algebra I math TEKS standards.
How many total questions are available?
1,113+ questions in our Algebra I Exponential Functions bank. Print as many 20-question worksheets as you like — each one pulls a fresh set so your kid doesn't see the same questions twice.
Where do these questions come from?
Generated by our AI pipeline, then quality-gated by two independent models (gpt-4o for content review, Claude Sonnet 4.5 for math verification) before publishing. Every question is tagged to a specific TEKS standard and modeled on real STAAR item shapes.
