Is this table a function? Yes, because every y is matched with only one x
Yes, because every x is matched with only one y.
No, because the table does not include the point (0, 0)
No, because the table is not proportional.

You buy five cds at a sale for $5.95 each. write an expression for the total cost of the cds.then use the distributive property and mental math to evaluate the expression.

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

Factor the polynomial by its greatest common monomial factor.
