Step-by-step explanation:

We can look at the table and figure out how we get f(5)

really its just the x value pugged into the x value for the function

On a map, 1/4 inch represents 12 miles. If a road is 66 miles long, what is its length, in inches, on the map?

it'll be 1(5)/(6) inches on the map

since 12 miles is a quarter of an inch, we need to see how much it will be for 66 miles. we divide 66 by 12, which gives us 5(1)/(2)

we multiply that by (1)/(4), which gives us thusly 1(5)/(6) of an inch = 66 miles.
