here is the question:
the rate of rainfall during a storm ' t ' hours after it began was 3 mm per hour when ' t ' = 5, 6 mm per hour when ' t ' = 9 and 5 mm per hour when ' t ' =13. Assuming that a quadratic model applies, find an expression for the rate, ' r ' mm per hour, in terms of ' t '.
PLEASE HELP!!
thanks soooo much
