Use the graphing calculator to graph the function f of x is equal to negative square root of x Which list contains three points that lie on the graph of the function?

For f(x) = −√x, x must be 0 or positive, and each output is the negative square root of x. Substituting x = 1, 4, and 9 gives f(1) = −1, f(4) = −2, and f(9) = −3. Thus the points (1, −1), (4, −2), and (9, −3) all lie on the graph, matching choice D.
