This SAT Sphere lesson focuses on essential SAT test topics in the Exponential Functions section. You'll build a strong understanding of core concepts, learn time-saving test-taking strategies, and apply your knowledge to realistic Digital SAT practice questions.
01
Introduction to Exponential Functions
Frames why exponential growth and decay matter on the Digital SAT and reminds students to recall prior skills: laws of exponents, evaluating powers, and basic graph reading from Coordinate Geometry.
02
Anatomy of an Exponential Function
Defines the general form f(x)=a·b^x, identifies initial value, base, and horizontal asymptote, and refreshes exponent-law notation from the earlier “Introduction to Exponents and Powers” lesson.
03
Modeling Exponential Growth
Explains how a base b > 1 produces rapid increase and shows students how to build growth formulas for populations, finance, and SAT-style word problems, extending proportional-reasoning ideas from Percentages and Ratios.
04
Modeling Exponential Decay
Introduces decay factors 0 < b < 1, connects half-life and depreciation scenarios, and mirrors the growth structure to reinforce pattern recognition across contexts.
05
Graphing Exponential Functions
Guides students in plotting key points, locating asymptotes, and interpreting intercepts, refreshing coordinate-plane skills from the Coordinate Geometry lesson.
06
Comparing Linear, Quadratic, and Exponential Growth
Contrasts constant difference, constant second difference, and constant ratio models to sharpen recognition of function types, building on earlier Linear Equations and Quadratic Equations lessons.
07
Solving Exponential Equations with Common Bases
Teaches students to rewrite both sides with the same base and set exponents equal, extending exponent-law fluency practiced in Simplifying Algebraic Expressions.
08
Solving Exponential Equations Using Logarithms
Introduces logarithms as inverse operations to isolate exponents and prepares students for the upcoming Logarithmic Functions lesson, while reinforcing properties of equality learned in Linear Equations.
09
Practice: Solving Exponential Equations
Provides SAT-style items that mix common-base and logarithmic methods, giving immediate feedback and revisiting sign management skills from earlier equation-solving practice.
10
Applications of Exponential Functions
Applies growth and decay models to finance, biology, and physics problems, reinforcing real-world translation techniques from Word Problems and Applications.
11
Key Takeaways and Targeted Practice
Synthesizes growth, decay, graphing, and equation-solving strategies into a concise checklist and offers mixed-question practice to cement mastery before advancing.
