Graph y = 4(x - 2)2 + 3 using transformations. 10어 y = 4(x – 2)² +3 8- Use a series of transformations on the graph of y=x2 to produce the graph of y = 4(x- 2)² + 3. The graph of y = x2 is shown to the right. (1,7) 4- (3,7) Begin by transforming y = x2 to y = 4x2. For a> 0, the graph of y = af(x) is a vertical stretch or compression of the graph of y= f(x). So, either a vertical stretch or compression will be used to change the graph of y = x2 to the graph of y = 4x2. 러 (2,3) -10-8 -6 -2 -2- 10 -4 -4- Note that for a>0, the graph of y = af(x) is a vertical stretch of the graph of y = f(x), if a> 1, and is a vertical compression of the graph of y = f(x), if 0<a<1. Hence, the graph of y = 4x² is a vertical stretch by a factor of 4 of the graph of y = x2. -8- 10 In the function y = 4x², the output of the function is being multiplied by 4. When an output of a function f(x) is multiplied by a positive number a, the graph of the new function y = af(x) is obtained by multiplying each y-coordinate on the graph of y = f(x) by a. Consider the three points on the graph of y = x2. Find the coordinates of the corresponding points that lie on the graph of the vertical stretch of the graph of y = x2 by a factor of 4. Multiply the y-coordinate by 4 and keep the x-coordinate the same. Points that lie on the graph of y = x2 Corresponding points that lie on the graph of y = 4x? (- 1,1) (0,0) (1,1) (- 1,4) (0,0) (1,4) Using the points found in the previous step, vertically stretch the graph of y = x2 by a factor of 4 to sketch the graph of y = 4x². The correct graph is shown to the right. Use a second transformation to change y = 4x2 to y = 4(x – 2)2. For h>0, the graph of y = f(x +h) is a horizontal shift of the graph of y = f(x). So, a horizontal shift should be used to change the graph of y = 4x2 to the graph of y = 4(x – 2)². Note that for h > 0, the graph of y = f(x – h) is the graph of f(x) shifted horizontally right h units, and the graph of y = f(x + h) is the graph of f(x) shifted horizontally left h units.
