In the figure to the right is the graph of a function f. Below are the graphs of six transformations of f and nine expressions that symbolically represent possible transformations. Find a graph that matches an expression. [Note: There will be three expressions without graphs.] Your answers should be in the form A-7, B-2, (-1,2) y=f (x) (1,-2) etc. А. В. С.

2. The new cookbook you just got gives all the oven temperatures in degrees Celsius but your oven uses degrees Fahrenheit. Additionally, your oven runs hot and you always have to decrease the prescribed temperature by 15° F. Write an expression using a composition of functions that will determine how high you have to preheat your oven when a recipe from your new cookbook calls for a temperature of t° F. (Hint: C-(F-32) and F=C+32 are the equations to convert between degrees Celsius C and degrees Fahrenheit, F.)
