1, big brother, your own picture is wrong, I corrected it.

2. Please see the screenshot for the specific picture.

3. Generally, the image of (1)y=-f(x) is an image in which y=f(x) is symmetric about x axis.

(2)y=f(x+a), when a≥0, the image of y=f(x) moves one unit to the left; When a < 0, the image with y=f(x) moves one unit to the right.

(3)y=|f(x)|, that is, all parts of the image where y=f(x) is below the x axis are turned up.

(4)y=f(|x|), on the basis of y=f(x), keep the image when x≥0, and then remove the image when x < 0, and draw a new image that is symmetrical about y with the image when x≥0.
