cabs use a valuable commodity—gas! research average gas prices from 2005– 2015 for the city you chose. if you can't find this information for your specific city, you can research national gas price averages instead.

a. create a table showing the average gas price each year.

b. create a scatter plot of the data in your table.

c. what equation models the data? what are the domain and range of the equation? do you think your equation is a good fit for the data? explain how you determined your answers.
d. is there a trend in the data? does there seem to be a positive correlation, a negative correlation, or neither? how much do you expect gas to cost in 2020

i think the answer is b

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
