Does this graph show a function? Explain how you know. A. No; there are y-values that have more than one x-value.
O B. Yes; the graph passes the vertical line test.
O C. Yes, there are no y-values that have more than one x-value.
O D. No; the graph fails the vertical line test.

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.
