Texas Instruments: Logarithmic Functions

Given an exponential or logarithmic function, the student will describe the effects of parameter changes.

In these questions, students identify asymptotes and removable discontinuities of rational functions, simplify rational expressions, and solve rational equations. Solutions and explanations are included.

These questions test knowledge of domain and range of exponential functions, properties of exponents, and population growth and compound interest modeled by exponential functions. Questions are true/false and multiple choice; solutions...

Students can use exponential functions to study growth and decay. Students will solve word problems ranging from population to interest rates.

Review inverse functions with your students using this TI-83 activity. Students will find inverses of given functions, determine whether the inverse is a function, graph both, and check for symmetry through the line y=x. The lesson...

This activity provides students an opportunity to discover the similarities involved in shifting the parent functions for absolute value, quadratic, cubic, radical, exponential, and logarithmic functions. Students will also be given the...

Using a TI-Nspire calculator, learners will work to better understand function notation and input/output functions. They write equations with a function symbols, identify what makes an equation a function, and graph lines in order to...

This clear tutorial provides the definition of a logarithmic function as well as instruction on how to perform important tasks with them. Find step-by-step solutions to example problems and practice exercises for you to complete and check.

In this activity students use the CAS tool to explore sin, cos, and tan functions. They expand the functions and find the domain. They also prove the conjectures.

In this activity, students investigate piecewise functions for continuity and differentiability.
