Cabs use a valuable commodity—gas! Research average gas prices from 2005–

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? Explain.

Answer 2

a lot.

Answer 3

a) Look at this figure, from your question you have to make a table just like this.
b) to make a scatter plot > click > http://www.virtualnerd.com/pre-algebra/linear-functions-graphing/scatter-plot-best-fit-lines/scatter-plots-predictions/scatter-plot-example

---- Learn from it and draw a scatter plot.
c) lets take an example: here population data shows,

now, just Write each population in scientific notation. Isn't it so simple ?
d) Trend of data depends on the graph you obtain, ref: http://www.regentsprep.org/regents/math/algebra/AD4/scatter.htm `

By 2020 gas will cost a lot if non renewable sources(re-usable) like petrol, diesel don't exist. @SarahLitts
