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

Graphing Functions Consider an equation such as y = 2x – 1 We say that y is a function of x because if you choose any value for x, this formula will give you a unique value of yFor example, if we choose x = 3 then the formula gives us y = 2(3) – 1 or y = 5 Thus we can say that the value y = 5 is generated by the choice of x = 3Had we chosen a different value for x, we would haveI'm just gonna do the, um, gonna focus on the positive side of the graph So X squared is gonna start at 00 One of the most scale, every to tick marks is one So one squared is one two squared is four So 1234 okay And three squared is is nine So is it 45 67 Right at the top of our page You have a mirror on the other side It's it's symmetrical around the y axis, I guess I said look about · The only difference with the first graph that I drew (y = x 2) and this one (y = x 2 − 2) is the "minus 2" The "minus 2" means that all the y values for the graph need to be moved down by 2 units So we just take our first curve and move it
