Translate the image of the first-order function y = 2x + 1 up one unit length, and then to the right two unit lengths? The expression of the function is
The image of the first-order function y = 2x + 1 is translated upward by 1 unit length, and y = 2x + 1 + 1 = 2x + 2 is obtained
Then translate 2 units to the right to get y = 2 (X-2) + 2 = 2x-2
The expression of the function is y = 2x-2
