Which best describes the function represented by the data in the table?
linear with a common ratio of 4
linear with a common second difference of 4
quadratic with a common ratio of 4
quadratic with a common second difference of 4

  quadratic with a common second difference of 4

Step-by-step explanation:

The only answer choice that is self-consistent is ...

  quadratic with a common second difference of 4

__

You don't even need to see the data table to choose the appropriate answer.

More explanation

A linear function will have a common first difference, not a common ratio or (non-zero) second difference. [eliminates choices A and B]

A quadratic function will have a common second difference (consistent with the last answer choice).

Any function with a common ratio is an exponential function. [eliminates choice C]

The quadratic with a common second difference of 4

answer: the first one

step-by-step explanation: use a calculator and divide the minutes by the dollars.

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
