Explore different types of functions using an interactive lesson. Learners enter functions and view the accompanying graphs. They can choose to show key features or adjust the scale of the graph.

Take the first step into graphing sequences. Learners set the starting number, multiplier, add-on, and the number of steps for a sequence. Using the inputs, the interactive calculates and plots the sequence on the coordinate plane. Users...

Study logarithmic properties using a triangle. A clever manipulative shows how a triangle can represent the three parts of a logarithmic or exponential equation. Pupils review the concept and then answer guiding questions to further...

Your young microbiologists will interpret and solve exponential equations in this real-world context task set in a hospital research scenario. Learners think in terms of the functions as well as their rates of change. 

This site explains Logarithms. The site has examples the student can examine and exmples the student can work and check online.

This problem introduces Carbon 14 dating which is used by scientists to date certain organic material. This version is based on the ratio of Carbon 14 to Carbon 12, which decreases at a constant exponential rate after an organism dies....

For this task, students investigate the power of exponential growth in this real-world example of an invasive species that was introduced to Florida in 1966, a giant snail. Aligns with F-LE.A.2 and F-LE.A.4.

In this task, students work with exponential functions in a real-world context involving continuously compounded interest. They will study how the base of the exponential function impacts its growth rate and use logarithms to solve...

Evaluate any logarithm in a calculator with the use of the change of base formula. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Solve exponential equations that have 2 or other numbers at the base of the exponential term. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Solve exponential equations that have 10 or e at the base of the exponential term. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

This is a 20 question quiz on logarithmic and exponential functions. This is a good way to be sure you know how to use logarithms and exponents. The site however only tells you if you've made a correct choice, there are no explanations.
