The graph shows the Dow Jones Industrial Average on a particularly tumultuous day soon after the U.S. credit rating was downgraded from AAA to AA+ in 2011. If t represents the number of hours the Dow Jones Industrial Average D as a function of time t. If we represent this function by D = f(t), use the graph to complete the following. Dow Jones Industrial Average I1,300 I1,200 I1,100 11,000 10,900 10,800 Down SO8 06 Close = 10,719.94 10,700 10,600 10 a.m. Noon 2 p.m. 4 pm. (a) Find f(0) and f(6.5) f(0) = 11228 (6.5) = 10719.94 (b) Find the domain and range for D = f(t) as defined by the graph. (Enter your answers using interval notation. Enter EMPTY or Ø for the empty set.) domain range (c) About how many t-values satisfy f(t) = 11,000? x t-values Estimate one such t-value.

The graph shows the Dow Jones Industrial Average on a particularly tumultuous day soon after the U.S. credit rating was downgraded from AAA to AA+ in 2011. If t represents the number of hours after 9:30 A.M., then the graph defines the Dow Jones Industrial Average D as a function of time t. If we represent this function by D = f(t), use the graph to complete the following. Dow Jones Industrial Average 11,300 11,200 11,100 11,000 10,900 10,800 Down 508.06 Close = 10,719.94 10,700 10,600 10 a.m. Noon 2 p.m. 4 p.m. (a) Find f(0) and f(6.5). f(0) = 11228 f(6.5) 10719.94 (b) Find the domain and range for D = f(t) as defined by the graph.
