Question 1109363: Decide which of the
Two given functions is liner and find its equation
x -10 0 10 20 30
F (x) -1.5 0 1.5 2.5 4.5
g (x) -7 -2 3 8 13

You can put this solution on YOUR website! Decide which of the
Two given functions is liner and find its equation
-----
Note:: Look for a common difference between consecutive terms.
-----
A(x) -10 0 10 20 30
common difference = (0--10) = 10
Since A(1) = -10, A(0) = -20
Equations:: y = 10x -20
----------------------------
F (x) -1.5 0 1.5 2.5 4.5
no common difference
-----------------
g (x) -7 -2 3 8 13
common difference = (-2--7) = 5
Since g(1) = -7, g(0) = -7-5 = -12
Equation: y = 5x -12
