You can certainly plot the graph by using values of x from 2 to 2 but I want to show you another way I expect that you know the graph of y = x 2 If you compare the functions y = x 2 and y = x 2 2, call them (1) and (2), the difference is that in (2) for each value of x the corresponding value of y is 2 less than in (1) Hence when plotting (2) the points on the graph of (1) are moved downSolution The parent function is y= 2x y = 2 x This graph has a yintercept at y = 1 y = 1 On the other hand, for y =2(2x) y = 2 ( 2 x) , the yintercept is at y = 2 y = 2 Illustration TheHere we are going to see, how to graph the function using transformations (ii) y = 2x Here the constant 2 is multiplied with x, so we have to perform dialation Since the positive constant is greater than one, the graph moves away from the xaxis 2 units (iii) y = x 1 Since 1 is added to the function, we have to translate the graph of y = x 1 unit upward (iv) y = (1/2)x 1 Step 1
