How does reflecting or rotating a figure change the interior angles of the figure?

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

The function f(x)= x5+ ( x + 3)2 is used to create a table. if x = -1 then what is f(x)?
