If f (x ) = 3 -x and g(x) = - 3 x -3 , find and simplify: (a) f(9) [1] (b ) ( f - g )(x ) [2] ( C ) [2] (d) fog(x) [2] f(a)- f(3-a) (e) f ( 6) [4] (f) the domain of fog(x) [1] 10. For the function y=f(x) to the right, sketch the graphs of: (a) g(x) = f(x+3)-2 [2] ( b ) 8 (x ) = 25 7 +2 [2] (c) g(x) =f-(x) [2] 11. In metal shop class, a student has to cut a 124 cm long metal strip into two pieces, one to form the side of a round cake pan and the other to form the side of a square cake pan. How should the strip be cut so that the sum of the areas of the pans is a minimum? [5]
