Trigonometric functions are written in general form according to the equations below, where the variable a is called the AMPLITUDE: f(x) a sin[b(x h)] + k = - f(x) = a cos[b(x h)] + k Match the following trig functions to their corresponding graphs: f(x) = 2 sin(x) f(x) = 3 cos(x) 3 f(x) = - 3 cos(x) a. f(x) = == 2 sin(x) /2 3/2 2 5/2 -2 -3 -4- + b.
