How can you tell the zeros of this function by looking at the graph? what are the zeros of the function? a)zeros occur at the minimum value. on this graph the zero is -10. b)zeros occur where the graph intercepts the y-axis. on this graph the only zero is -9. c)zeros occur where the graph intercepts the x-axis. on this graph the zeros are -1, 1, and 3. d)zeros occur where the graph intercepts the x-axis. on this graph the zeros are -1, 0, 1, and 3.
