What is the function equation for the input/output table? x y 2 10 5 13 8 16 11 19

ANSWER

EXPLANATION

We can see that, the difference in y-values from the table is 3

Also the difference in the x-values is 3.

Hence the slope is

Let y=mx +c be function equation.

We put m=1 to get,

From the table when x=2, y=10.

This implies that,

Hence the function equation is

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
