. Births The number of births to females in the UnitedStates between 15 and 17 years of age can bemodeled by the cubic function y = 0.0790x3 -2.103x2 + 10.695x + 179.504, where y is the number of thousands of births and x is the number ofyears after 1990. The model indicates that 155,154births occurred in 2000; find another year after1990 when the model indicates that 155,154 birthsoccurred.
