Which of the following is the graph of y = negative StartRoot x EndRoot + 1?
On a coordinate plane, an absolute value curve curves up and to the right in quadrant 4 and starts at y = 1.
On a coordinate plane, an absolute value curve opens down and to the left in quadrant 2 and starts at y = negative 1.

A.
Reason: y = −√x + 1 is defined for x ≥ 0 and at x = 0 gives y = 1, so the graph starts at (0,1). As x increases √x grows, so −√x + 1 decreases — the curve goes down and to the right (entering quadrant IV for large x). Option B is wrong because the graph does not go left and does not start at y = −1.
