About this resource

What's inside this resource

This is an Exponential + Logarithmic Characteristics Worksheet that will give students practice with finding characteristics.

There are 8 problems - 4 per page.

Students will complete the characteristics for each function that is given as an equation. They can show any necessary scratch work on a separate sheet of paper.

Teaching tips & learning objectives

Learning objectives

  • State the domain and range of an exponential or logarithmic function in interval notation
  • Identify the horizontal or vertical asymptote of a transformed exponential or logarithmic function
  • Find the x and y intercepts of a transformed exponential or logarithmic function
  • Determine intervals of increase and decrease
  • Describe end behaviour as x approaches infinity and as x approaches the asymptote

Teaching tips

  • The graph problems and the equation problems are separate sections, so you can assign the graph half first and the equation half as the follow-up
  • The instructions tell students to do scratch work on a separate sheet, so there is no working space built into the page
  • The key uses interval notation consistently, which makes it a good model for students who are still writing domains in words

Skills covered

  • analysing exponential functions
  • analysing logarithmic functions
  • interval notation
  • asymptotes
  • end behaviour
  • intercepts of transformed functions

Good to know

Questions teachers ask about this resource

Is an answer key included?

Yes - a completed KEY version of both sheets with every field filled in.

What level of maths is this?

Algebra 2 or Precalculus - roughly Grade 10 to 12. It assumes interval notation, transformations and end behaviour are already familiar.

How many problems are there?

Eight - four read from graphs and four worked from equations.

Are there other versions of this worksheet?

The footer marks this as Version 1, which implies other versions exist, but only this one is in the download.
