Question

The average retail price of gas in America from 1979 to 2008 can be modeled by the function

P (x) = 0.008x³ - 0.307x² + 4.38x + 25.72

Where P is the price of gas in cents per litre and x is the number of years after 1979

Determine the average price of gas in 2002.

a.) 69.8¢/L

b.) 71.7¢/L

c.) 70.4¢/L

d.) 68.8¢/L

Answer 1

This is the same as your other post.

23 * 4.38 = 100,74

25.72 + 100.74 = 126.46

Review the accuracy of the choices.
