Hello can someone please help me this is a 2 part question and i have been working on it for hours.

v v v 1. The graph below shows the Canadian CPI in triangles from 19702019. The black dots are New Brunswick Minimum Wage data which we will not use for this activity. 130 - 120- - 12 110- - 11 100 - - 10 90 - -9 80- -8 CPI Minimum Wage 70- 60- 50 - -5 40 - -4 30- -3 20 - -2 . 10- -1 1969 1971 1973 1975 1977 1979 1981 1983 1985 1987 1989 1991 1993 1995 1997 1999 2001 2003 2005 2007 2009 2011 2013 2015 2017 2019 Date (a) [2 marks] There are roughly two epochs in CPI (the inflation rate changes in 1991). Fit each epoch with its own exponential function of the form f(t) = Aebt by using the data points at the start and end of each epoch. For each epoch, define the independent variable t as equaling zero at the year that starts the epoch. For example, for the first epoch, t would be equal to the Date minus 1970. (b) [2 marks] Calculate the rate of increase (growth rate) of CPI (i.e. inflation). v v v 1. The graph below shows the Canadian CPI in triangles from 19702019.
