Ch 0 Graphing Functions by Esther Infinity




In our Ch. 0 Graphing Functions Project, we illustrated the different transformation graphs of five different functions.
1. The original parent function is y = x2.
2. The vertical translation, with a function of y = x2 - 3, is shown in blue. I moved the parent function down 3 units.
3. The horizontal translation, with a function of y= (x - 3)
2 , is shown in red. I moved the parent function 3 units to the right.
4. The vertical + horizontal translation, with a function of y = (x - 3)
2 - 3, is shown in purple. I moved the parent function 3 units to the right and 3 units down.
5. The horizontal reflection, with a function of y = (-x)
2 , is shown in pink. I flipped the parent function graph across the x-axis.
6. The vertical reflection, with a function of y = -x2 , is shown in green. I flipped the parent function graph across the y-axis. Also, since the parent function and the horizontal reflection would equal the same, they have the same graph.
7. The vertical + horizontal translation + vertical reflection, which a function of y = | x - 3 | - 3, is shown in orange. I flipped the vertical + horizontal translation function (purple) across the y-axis.

Hiiiiii! You described so much. I like your wonderful drawings
