Consider the function represented by 9x+3y=12 with x as the independent variable. how can this function be written using
function notation?
o fly = - žv+
of(x) = - 3x + 4
of(x) = -x +
fcv) = - 3y + 4

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
