The table respent two linear functions the equation respented by the first tables is given

Come up with a new linear function that has a slope that falls in the range 10 m − < < . choose two different initial values. for this new linear function, what happens to the function’s values after many iterations? are the function’s values getting close to a particular number in each case?

Which expression gives the area of the triangle shown below
