A ball is thrown upward from a 48-foot building. Its height is modeled by h(t)=−16t2+32t+48. When solving h(t)=64 to find when the ball is 64 feet high, a student obtains t=0.5 and t=1.5. The student discards t=1.5, reasoning that "the ball can only reach 64 feet once on its way up." Which assessment of this reasoning is most appropriate?
