Which statement correctly compares the two tables?

Let's work it out together.

Work through one checkpoint at a time. Your answer area opens after the reasoning.

Checkpoint 1

Check consecutive differences for a linear pattern.
Checkpoint 2

Check consecutive nonzero ratios for an exponential pattern.
Checkpoint 3

Increasing alone does not identify a model family.

Function A is exponential because it has a constant difference.Both functions are linear because each has one output per input.Function B is exponential because it has a constant ratio.Function B is linear because its outputs increase.
