subject: Characteristics of an Exponential Equation

please help me to answer those questions below In the box

MBF3C Lesson 7 Assignment In this assignment you are going to explore the characteristics of exponential functions (growth or decay) Make sure you answer all questions in the spaces provided For each question, answer the question giving the clues that you used in determining your answer. You will be given two marks - one mark for your correct clues and one mark for the correct answer. 1. Which graph could represent an exponential relation? a. C. b. Page 1\f10. 11. Which equation best represents this graph? I _______________________________________________ _| 3- y= 4(2)' Which equation best represents this graph? b.
