They cause a vertical shift down that many units.
y=x^2 and y=x^2-3 are graphed below the -3 caused a vertical shift down 3 units
Y=|x| and y=|x|-3 are graphed below and the -3 caused the same vertical shift down three units.
:
When the 3 is subtracted from the x it causes a horizontal shift to the right three units.
y=x^2 and y=(x-3)^2 are graphed below.
y=|x| and y=|x-3| are graphed below.
Happy Calculating!!!
