QUESTION In the diagram below the graphs of f(x) = a cos bx and g(x)=sin (x + p) are drawn for xe [-180°,180). -180 -135 -90 0 90 180 -1 3.1 3.2 Write down the values of a, b and p. (3) of g increases? For which values of x in the given interval does the graph of ƒ increase as the graph (2) 3 Write down the period of ƒ (2x). (2) 33.4 Determine the minimum value of h if h(x)=3(x)-1. (2) 3.5 Describe how the graph g must be transformed to form the graph k, where k(x)=-cos x.
