WebIn order to graph a function, you have to have it in vertex form; a (x-d)² + c <---- Basic Form. Example: (x-3)² + 3. Since there's no a, you don't have to worry about flipping on the x axis and compressing or stretchign the function. Now we look at d. d = -3. In order to find the zeros of the function, x must equal 3. WebNov 25, 2024 · Abstract.
