What is the period of: {{{y = sin(2x + 1)}}} . . . . . . {{{graph(600,300,-10,10,-3,3,sin(2x + 1))}}} Period: {{{2(pi)/b}}} Period: {{{2(pi)/2}}} Period: {{{pi}}} What is the range of: {{{y = 2*sin(-3x + 2) + 1}}} . . . . . . {{{graph(600,300,-10,10,-3,4,2*sin(-3x + 2) + 1,1)}}} d = 1 ~> so the horizontal axis is at ~> y = 1 a = 2 ~> the amplitude is two units, so the highest points is two units above and below the horizontal axis ~> y = -1 and y = 3 Range: {{{-1 <= y <= 3}}} What is the horizontal shift of: from: {{{y = -0.75*sin(x) + 1.61}}} to: {{{y = -0.75*sin(x + 1.7) + 1.61}}} . . . . . . {{{graph(600,300,-10,10,-3,3,-0.75*sin(x) + 1.61,-0.75*sin(x + 1.7) + 1.61)}}} c = 1.7 -c = -1.7 1.7 units left
