Find all explicit solutions y = ϕ(x) of the de in part (a) defined by this relation. give the interval i of definition of each explicit solution. (enter your answers for i using interval notation.) ϕ1(x) = (solution in quad i) i = (domain of ϕ1) ϕ2(x) = (solution in quad ii) i = (domain of ϕ2) ϕ3(x) = (solution in quad iii) i = (domain of ϕ3) ϕ4(x) = (solution in quad iv) i = (domain of ϕ4)
