Consider this input/output table.


(a) Graph the values from the table by taking input along horizontal axis from 0 to 8 and Output along vertical axis from 0 to 24.


(b) Use your graph to predict the outputs for inputs of 3 and 8.

(a) Let as plot the graph as per the given table. It is shown as below



This graph follows y = 3x-1 pattern.


(b) The graph follows y = 3x-1 pattern.


If x = 3 then y = (3 ×3)-1 = 5


If x = 8 then y = (3 ×8)-1 = 23
