Question

Which is the graph of the function f(x) = Negative StartRoot x EndRoot

On a coordinate plane, an absolute value graph starts at (0, 0) and goes down and to the right through (4, negative 2).

On a coordinate plane, an absolute value graph starts at (0, 0) and goes up to the left through (negative 4, 2).

On a coordinate plane, an absolute value graph starts at (0, 0) and goes down and to the left through (negative 4, negative 2).

On a coordinate plane, an absolute value graph starts at (0, 0) and goes up and to the right through (4, 2).

Answer 1

The first one: the curve that starts at (0,0) and goes down and to the right through (4, −2).

Reason: f(x) = −√x is defined for x ≥ 0, equals 0 at x=0, and f(4) = −2, so it lies below the x‑axis and decreases as x increases.
