Question

In 1990, a country imported 275 million pounds of pasta. From 1990 to 2000 imports increased by an average of 42 million pounds per year. (a) Use these data to express q, the country's annual imports of pasta (in millions of pounds), as a linear function of t, the number of years since 1990. q(t) = (b) Find the 4-year moving average of your model. q?(t) = (c) What can you say about the slope of the moving average? It is smaller than the slope of the original function. It is larger than the slope of the original function. It is the same as the slope of the original function.
