Thank you for the help Solution Have a look at the number that is multiplying x in your function, i.e., ; is given by /|b|. Since: period = 1 Use the form a tan(bxc)+d to find the amplitude, period, phase shift, and verticalshift. Vertical Asymptotes: x=(1/2)+ n, where n is an integer Amplitude: None Period: 1 Phase Shift: 1 (1 to the right) Vertical Shift: x =1,5/4,7/4,2,9/4 y=0,1/5,-1/5,0,1/5 graph is last one i.e d).
