1. Consider the quadratic function f(x) = 23::2 + 12x + 17 (a) Express f in the standard form f(x) = :10: h)2 + k. (1)} Sketch the graph of f. Your sketch should show the correct shape of the graph and the axes should be properly labelled. (e) State the domain and range of f. ((1) Find the maximum or minimum value off and state whether it is a maximum value or a minimum value. [6]
