Sketch the graphs of f and g in the same coordinate plane. (Include two full periods.)f(x) = 5 sin ?xg(x) = 5 sin ?x - 4Step 1To sketch the graph of a function, first find its amplitude and period.Recall that the amplitude and period of curves of the form y = a sin bx and y = a cos bx are given by amplitude = |a| and period =2?/bTherefore, the amplitude of the curve f(x) = 5 sin ?x is and the period is
