how can you graph absolute value functions without calculators or plotting points?

Question

cruffo · Answer

Use the basic shape (a "V") that goes through the points (0,0), (1,1) and (-1,1) and transformations (shifting up/down, left/right, reflections, stretches and compressions)

how would i be able to figure out where i start or the curve of the parabola

cruffo · Answer

a parabola is not the same thing as an absolute value:

$\large y = x^2$ is the parabola, the "U" shape)

$\large y = \vert x\vert$ is the "V" shape.

Both of these basic graphs have the same 3 starting points (0,0), (1,1) and (-1,1).  But the points are connected with a different shape.
