A graph of two functions is shown below:

Which of the following is an approximate solution for f(x) = g(x)?
x = −2
x = 0
x = −1
x = 1

The customer price index(cpi), which measures the cost of a typical package of customer goods, was 208.8 in 2011 and 244.1 in 2016.let x=11 corresponding to the year 2011 an estimate to cpi into 2013 and 2014. assume that the data can be modeled by a straight line and the trend to continue idenfinitely. use data points to find such a line and then estimate the requested quantities
