The graph shows the equation x²+ y'= 5. Use the slider for a to move the vertical line on the graph. Based on the vertical line test, is this equation a function? Why or why not?

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.
