He can collect 6 pieces of firewood per excursion and each excursion takes 2 minutes. Which equations will model how many pieces of firewood he can collect with respect to number of excursions, how many excursions he takes with respect to time, and number of pieces of firewood with respect to time? let f be pieces of firewood let e be number of excursions let t be time in minutes OF(e) = be E(t) = t/2 F(t) = 3et OF(e) = be E(t) = t/2 F(t) = 3t OF(e) = e/6 E(t) = 2t F(t) = t/3 OF(e) = be E(t) = 2t F(t) = 12tQuestion 8 (1 point) Given the composite function h (x ) = gff(x) -2, what are the possible equations for g(x) and f(xx).
