Draw the graphs of the linear funcations...

Draw the graphs of the linear funcations (i) f (x) = 1 -x (ii) f(x) = 2x+1

Text Solution

Verified by Experts

When f (x) =1 x, some of the points on the graph are ( 0,1) , ( 1,0) ,( 2,-1) , (-1,2) etc.
Joining these points, we get a line as the graph of the function.
(ii) Let f(x) = 2x +1
Some of the points on the graph are (0,1), (1,3) , ( -1,-1) ,( 2,5) etc.
Joining these points, we obtain a line as the graph/.
