Funding for NASA: 1966-2015 The percentage of the U.S. federal budget allocated to NASA from 1966 to 2015 can be approximated by p ( t ) = 0.03 + 5 t 0.6 percentage points ( t ≥ 1 ) ( t is time in years since 1965 ) . 13 The following graph shows the data with the model: a. Find an appropriate domain of p . Is [ 0 , 50 ] an appropriate domain? Why or why not? b. Compute p ( 40 ) accurate to two decimal places. What does the answer say about the budget allocation to NASA? c. If the model is extrapolated to larger and larger values of t , what does it suggest about long-term financing of NASA?
