To find if the table follows a function rule, check to see if the values follow the linear form y = a x + b. y = a x + b. Here are some simple things we can do to move or scale it on the graph: We can move it up or down by adding a constant to the y-value: g(x) = x 2 + C. Note: to move the line down, we use a negative value for C. C > 0 moves it up; C < 0 moves it down Thus a function rule with two-step rules is used to fill in a table with x and y values.
