Woah…check this out
Exponential functions might sound like they belong in a science lab, but they’re actually pretty simple once you know what’s going on. The SAT loves testing your knowledge of exponential functions because they show up all over the place in real life—things like population growth, interest rates, or how fast things decay. And don’t worry, even if test anxiety or SAT anxiety kicks in, we’ll break it down step by step so you feel totally confident.
Let’s dive into the world of exponential functions and figure out exactly what each part means and how to handle different types of problems that might pop up on the SAT.
Step 1: What Is an Exponential Function?
Step 2: Finding the Y-Intercept
Step 3: Percent Increase and Decrease
Example 1: Percent Increase
Example 2: Percent Decrease
Step 4: Understanding the Growth Factor
lf, just think: is the number bigger than 1? Then it’s growing. Smaller than 1 (but still positive)? Then it’s shrinking.
Step 5: Practice Problems
Test Anxiety Tip: Take It Step-by-Step
When test anxiety kicks in, it’s easy to feel overwhelmed by all these parts and numbers. But remember, it’s all about knowing what each part of the function means and taking it one step at a time:
Final Thoughts
Exponential functions might seem tricky, but with a little practice and some careful reading, you’ll be able to handle them with ease. Remember, the key is to understand each part of the function and how it all fits together. Whether it’s finding the y-intercept, identifying the growth factor, or handling percent increase/decrease problems, you’ve got this!
Take a deep breath, trust your skills, and go crush that SAT!
