1. How does the degree of the sum or difference of two polynomial functions compare with the degree of the individual functions? [C1] 2. Explain why when you divide functions, there could be restrictions on the domain. [C1] 3. Explain how you can predict the locations of the zeros of (f x g) (x) before you construct a table of values or a graph? [C1] 4. Given f (x) = 2x2 + x and g(x) = x2 + 1 find the following: a) (f . g)(-2) b) g '[f (2)] [K6]5. Given the graphs of f(x) and g(x), a) Draw the graph of (f - 9)(x).
