Question

Which graph represents y = StartRoot x EndRoot?
On a coordinate plane, a parabola with a vertex at (0, 0) opens up.
On a coordinate plane, a curve that begins at (0, 0) opens down and to the right in quadrant 1.
On a coordinate plane, a cubic function is vertical and goes through (0, 0).
On a coordinate plane, a cubic function is horizontal and goes through (0, 0).

Answer 1

The second graph: the curve that begins at (0,0) and opens down and to the right in quadrant I.

Reason: y = √x is defined only for x ≥ 0, starts at (0,0), increases to the right but with decreasing slope (concave down), so it lies in quadrant I and looks like a right-opening, downward-curving arm.
