3. If f(x) = cot x and g(x) = sin x, which of these statements is true? a. f(x)g(x) = cos x b. f(x)g(x) = cotx 4. The zeros of a function g(x) appear on the graph of y a. x-intercepts b. holes = f(x) g(x) as C. f(x)g(x) = csc x d. f(x)g(x) = tan x C. vertical asymptotes d. B or C

Graph f, g, and h in the same rectangular coordinate system for 0sxs 2r. Obtain the graph of h by adding or subtracting the corresponding y-coordinates on the graphs of f and g. f(x) = - 3 sin x, g(x) = sin 2x, h(x) = (f+ g)(x) (--. Choose the correct graph. f(x) = - 3 sin x is the blue dashed curve, g(x) = sin 2x is the red dotted curve, and h(x) = (f + g)(x) is the black solid curve. O A. O B. Oc. OD. AY 41 -2n 4
