They grow by leaps and bounds. Learners watch a quick review on function notation as they prepare to learn more about exponential growth. Using their knowledge from sequences, pupils find out whether a function is linear or exponential, along with finding values for the function to sketch a graph. Scholars finish out the lesson by working with percent increase problems to find the equation or the percent of increase. Individuals use the activity to practice the newly learned skills.
