- Suppose that during the period 1990–2001, U.S. imports of pasta increased from 300 million pounds in 1990 (t = 0) by an average of 35 million pounds/year. (a) Use these data to express q, the annual U.S. imports of pasta (in millions of pounds), as a linear function of t, the number of years since 1990. q(t) = (b)Use your model to estimate U.S. pasta imports (in millions of pounds) in 2006, assuming the import trend continued. _________million poundsarrow_forwardSuppose that during the period 1990–2001, U.S. imports of pasta increased from 270 million pounds in 1990 (t = 0) by an average of 50 million pounds/year.

The win-dow should give a picture of the overall behavior of the function. There is more than one choice, but incorrect choices can miss impor-tant aspects of the function. 5. ƒ(x) = x4 - 4x3 + 15 6. ƒ(x) = x5 - 5x4 + 10 7. ƒ(x) = x sqrt(9 - x2) 8. ƒ(x) = x3 /3 - x2/ 2 - 2x + 1 9. ƒ(x) = 4x3 - x4 10. ƒ(x) = x2(6 - x3)arrow_forwardIn Exercises 57–62, find the zeros of ƒ and sketch its graph by plotting points.

Here, t is time in years since the start of 2000, and C(t) is the median home price in thousands of dollars. The locations of stationary points and points of inflection are indicated on the graph. Analyze the graph's important features, and interpret each feature in terms of the median home price. The median home price was $_________ thousand at the start of 2000 (t = 0). The median home price has two low points; first in the year_______ and again in the year___________ when it stood at $________ thousand; The median home price peaked at the start of the year__________ at $_________ thousand. The median home price was decreasing most rapidly at the start of the year__________ when it was $___________ thousand, and increasing most rapidly at the start of the year__________ when it was $_________ thousand.
