The domain of a relation is a. the output (y) values of the relation b. the input (x) values of the relation c. a set of points that pair input values with output values d. x and y values written in the form (x, y)

Sketch the vector field vector f( vector r ) = 8vector r in the xy-plane. select all that apply. the length of each vector is 8. the lengths of the vectors decrease as you move away from the origin. all the vectors point away from the origin. all the vectors point in the same direction. all the vectors point towards the origin. the lengths of the vectors increase as you move away from the origin.
