Which could be the function graphed below? On a coordinate plane, a curve opens down and to the right in quadrants 1 and 4. The curve starts on the y-axis in quadrant 4 and goes through the x-axis into quadrant 1.
f (x) = StartRoot x EndRoot minus 2
f (x) = StartRoot x minus 3 EndRoot + 1
f (x) = StartRoot 2x + 4 EndRoot
f (x) = StartRoot x + 1 EndRoot + 8
