Whаt is the degree оf the pоlynоmiаl shown? The x-аxis spans from below 0 to 10, and the y-axis spans from negative 20 to just above 20. The x-axis has a scale of 5 in increments of 1 and the y-axis has a scale of 10 in increments of 2. The purple parabola opens upward, with its vertex at approximately (3.5, negative 19). The curve is symmetric around the vertical line passing through the vertex. It intersects the y-axis at (0, 20). It crosses the x-axis at (1, 0) and (6, 0), extending out of view at both ends.
