Enrollment in a dance studio has grown exponentially since the studio opened. Below is a graph depicting this growth. Determine the average rate of change from x = 0 to x = 8. An exponential graph has time in years on the x axis and enrollments on the y axis. An upward rising curve begins at zero comma twenty and passes through eight comma one hundred and twenty. 120 0.08 20 12.5 Question 8(Multiple Choice Worth 1 points) (03.03 MC) The annual growth of Noah's worm collection is represented by the table.
