Does this set of ordered pairs represent a function? Why or why not? (-2,2), (-1, 2), (3, -1), (3, 1), (4, 11))
OA. Yes, because there are two xvalues that are the same.
O B. Yes, because every xvalue corresponds to exactly one y-value.
O C. No, because two of the y-values are the same.
OD. No, because one xvalue corresponds to two different y-values

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.
