Drawing method of image with absolute value How to draw the image when f (x) has absolute value? How to draw an image with absolute value of independent variable x?
F (x) image drawing method:
Draw the image of F (x), keep the image above the x-axis unchanged, and fold the image below the x-axis with the x-axis as the symmetry axis to get the image of F (x)
F (| x |) image drawing method:
Draw the image of F (x), keep the image on the right side of Y axis unchanged, erase the image on the left side of Y axis, and then fold the image on the right side of Y axis symmetrically to get the image of F (| x |)
