Question 962271: Please help me with this data analysis:
1.The median income in dollars of U.S households from 2000 to 2007 can be approximated by the model:I=187.65t^2-119.1t+42,013,0<=t<=7 where t represents the year,with t=0 corresponding to 2000
Graph this model,then use the graph to determine in which year the median reaches or surpassed $45,000.
