Finding Equations of Exponential Graphs
Finding Equations of Exponential Graphs
A PowerPoint lesson designed to help students learn how to find the equations of exponential graphs.
This lesson guides students through a clear, step-by-step process for identifying the important features of an exponential graph and using these features to write its equation.
This resource includes:
✓ Discussion questions to introduce exponential graphs
✓ A clear explanation of two useful equation forms
✓ A simple visual process for finding an equation from a graph
✓ Identifying the horizontal asymptote
✓ Finding the horizontal shift using the “corner stone” coordinate
✓ Finding the base using patterns in the graph
✓ Worked examples
✓ A reflected exponential graph example
✓ Student practice activities (“You try” questions)
✓ A decaying exponential graph example
✓ An algebraic method for finding exponential equations from coordinates
✓ A discussion question exploring equivalent exponential equations
