Which function corresponds to the table?

The values of the variables in the table can be generated by a function, given that each input has exactly one output.

The function that corresponds to the table is C) y = -2·x + 3

Reasons:

To determine the type of function, the first difference between the y-values in the table are found as follows;

The difference between the consecutive y-values are;

1 - 3 = -2

-1 - 1 = -2

Therefore, the first difference is constant, therefore, the function is a linear function.

The equation of the function in point and slope form is therefore;

y - (-1) = -2·(x - 2)

y = -2·x + 4 - 1 = -2·x + 3

y = -2·x + 3

Therefore, the function that corresponds to the table is C) y = -2·x + 3
