Write equations that represent the transformed functions described below:
(a) f(x) =√x is shifted left 4 units and vertically compressed by a factor of or 1/3
(b) f(x) =√x is vertically stretched by a factor of 4 and then shifted 3 units up
(c) f(x) =√x is shifted left 2 and then shifted 6 units down
(a) f(x) = (1/3)√(x-4)
(b) f(x) = 4√(x+3)
(c) f(x) = √(x-2) - 6
