Question

What is the function rule that describes the pattern in the table? X: -2 -1 0 1 2 Y: -5.3 -2.45 0.4 3.25 6.1

Answer 1

We can see in the "x" function, the numbers are moving (+1).

The first thing that we would do is to subtract both (-5.3 - -2.45) and our answer would be -2.85.

So, for every (+1) on the x function, the y function would (-2.85).

y= (-2.85)

x (+1)

Answer 2

the function rule is y=2.85x+0.4
