Honors Analysis

 Mr. Manker is traveling to California. He drives at a constant pace: 100 miles the first two hours 210 miles the next three hours 240 miles the next four hours Create a graph showing his distance and time

 What is the domain of the function? The range?  Write the equation of the function for distance (after time t hours) using piecewise notation  What is Mr. Manker’s rate of change (speed) on the interval (0, 2)?  What is his speed on the interval (2, 5)?  What is his speed on the interval (5, 9)?  What aspects of this scenario aren’t realistic? Why?

 Write the domain and range using interval notation:

 Give the domain and range using interval notation:

 The post office offers flat-rate mailing of packages: $1.50 for a package weighing less than 4 oz, $2.50 for a package weighing 4 oz to less than 8 oz, and $3.50 for a package weighing 8 oz to 12 oz.  Graph this function. Is it continuous? Explain.

A t-shirt company sells t-shirts for $8 apiece if five or fewer are sold, $6 apiece if 5-10 are purchased, or $5 apiece if more than 10 are purchased. Why is this considered to be a DISCRETE function? Sketch a graph.

Solve for k so that function f is continuous:

 Solve for k so that f is continuous:

Jose left the airport and traveled toward the mountains. Kayla left 2.1 hours later traveling 35 mi/hr faster in an effort to catch up to him. After 1.2 hours Kayla finally caught up. Find Jose’s average speed.

 Two cars 276 miles apart start to travel toward each other. They travel at rates differing by 5 mi/hr. If they meet after 6 hours, find the rate of each.

A boat traveled 336 miles downstream and back. The trip downstream took 12 hours. The trip back took 14 hours. What is the speed of the boat in still water? What is the speed of the current?
