MHF 4UB Workbook Unit 1 To identify whether a given graph shows an exponential function or a polynomial function. b) Explain how to identify whether a given equation represents an exponential function and how to determine the base of the function. c) Explain how to distinguish between exponential growth and decay in both graphs and equations of exponential functions. Thinking/Inquiry/Problem Solving [16 marks] [Next page provides grids for (b) and workspace.] Match each of the following functions with its graph, and explain why the function describes the graph. Note that the graphs are all drawn with different window settings but the same scale on the axes. f (x) = -50 8(x)=4-+25 h(x) =3 +5 j.(x)=-7(6) -10 MHF 4UB Workbook Unit 1 : b) .Sketch the graphs for each of the following functions, Remember to identify all of the key features before. you start your sketch. .i) 1 -10 i) y = 3(4) +9. c) Explain how you would sketch the graph of y = -3(5) + 12 MHF 4UB Workbook Unit 1." on [2 marks]. On the following graph, an exponential function is drawn and the line y = x is given. Sketch the inverse function for this function. Journal: Lesson 2 CamScanner
