How do you find the domain & range for #y=tan4x#? Trigonometry Graphing Trigonometric Functions Amplitude, Period and Frequency 1 Answer Diana S. · Roella W. Nov 10, 2015 domain is all real values.......since it is in form of# tan(y)# where #y=4x# and the range #=R-{(2n+1)pi/8}# Explanation: domain is clear range is #y=R-{(2n+1)pi/2}# # 4x=R-{(2n+1)pi/2}# # x=R-{(2n+1)pi/8} # Answer link Related questions How do you find the period and frequency of a sine function?
