11th Grade Exponential & Logarithmic Functions Worksheets
Graph, analyze, and apply exponential and logarithmic functions.
About Exponential & Logarithmic Functions
Exponential and Logarithmic Functions introduces two of the most important function families in all of mathematics. Students graph and analyze exponential growth and decay, understand logarithms as the inverse operation of exponentiation, apply logarithm properties to expand and condense expressions, solve exponential and logarithmic equations, and work with the natural base e and the natural logarithm. These functions appear in virtually every quantitative field.
Why Exponential & Logarithmic Functions Matters for 11th Grade
For 11th Grade students, exponential and logarithmic functions represent a significant expansion of the mathematical universe — from polynomial functions (which grow at a steady algebraic rate) to functions that can grow or decay at dramatically accelerating rates. The applications are everywhere: exponential functions model population growth, viral spread, radioactive decay, and compound interest. Logarithms make multiplicative comparisons additive, which is why they are used in the decibel scale, pH scale, and Richter scale. Mastery of this unit is essential for both calculus and quantitative careers.
Choose a Subtopic
The unit begins with exponential functions — their graphs, key features, and growth/decay behavior. Logarithms are introduced as inverses of exponentials, so students have both operations available. Logarithm properties provide the algebraic tools for manipulating logarithmic expressions. Solving equations combines all prior skills. The unit culminates with the natural base e and the natural logarithm, which provide the most important special case and are essential preparation for calculus.

The most important conceptual moment in this unit: a logarithm answers the question "what exponent gives me this value?" If students grasp this, the rest follows naturally.
Logarithm properties (product, quotient, power) are directly analogous to exponent laws — help your student see the parallel, as it makes them much easier to remember.
The number e (approximately 2.718) is not arbitrary — it is the base for which the exponential function has a slope of exactly 1 at x = 0. This special property makes it the natural choice for all continuous growth and decay models.
Extraneous solutions are particularly common in logarithmic equations because the domain of a logarithm excludes non-positive inputs. Always check solutions.
Connect exponential functions to current events: any news story about population, disease spread, or compound interest can become a problem-solving opportunity.
