The graphs show the distance, d, traveled by two cars, A and B, over time, t. Distance is measured in miles and time is measured in hours.

Which car traveled slower?

The graphs show the distance, d, traveled by two cars, A and B, over time, t. Distance is measured in miles and time is measured in hours.

Explain how you know. In other words, justify your answer to #1.

Here are descriptions of four situations in which the volume of water in a tank is a function of time. Match each description to a corresponding graph.

Tyler filled up his bathtub, took a bath, and then drained the tub. The function gives the depth of the water, in inches, t minutes after Tyler began to fill the bathtub.

These statements describe how the water level in the tub was changing over time. Use the statements to sketch an approximate graph of function. We have talked about Tyler and his bath a lot in the last week. Now graph it out! Yes, there will be a couple of extimate moments, but the facts above should be evident.

Two functions are defined by these equations:

f(x)=5.1+0.8x

g(x)=3.4+1.2x

Which function has a greater value when x is 3.9? How much greater? Format like "h(x) is greater by 20.5" for instant grading.

Function f is defined by the equation f(c)=3c-7. Find the value of c so that f(c)=20 is true.

A(t) is the average high temperature in Aspen, Colorado, t months after the start of the year. M(t) is the average high temperature in Minneapolis, Minnesota, t months after the start of the year. Temperature is measured in degrees Fahrenheit.

Which function had the higher average rate of change between the beginning of January and middle of March?

Here are two graphs representing functions f and g.

Select all statements that are true about functions f and g.

So what does that tell us in the context of the problem?

Which runner?

Brighten my day and use a pretty color. Should have a dot for every point on your chart.
