The graph shown represents the height (h) of a hiker during a period of time (t). Use the vertical line test to determine if the relation represented on the graph is a function. Complete the explanation. since___vertical line will pass through more than one point, the graph_the vertical lines test so the relation_ a function

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.
