A photo processing lab lists the following prices to reprints: $.32 for a 3x5 print; $.45 for a 4x6 print; and $.75 for a 5x7 print. a) Find a quadratic function that models the cost per print in terms of the smaller dimension of the print size.

b) Using this model, find the approximate price of a 7x9 print.
