Question

The function f(x) is to be graphed on a coordinate plane
At what point should an open circle be drawn?
(–1, 0)
(0, 0)
(0, 1)
(1, 0)

Answer 1

the correctttt answeerrrr is 0,0

Answer 2

The correct answer is:

(0, 0)

Explanation:

The first equation in the system is f(x) = -x, for x < 0.  This means when x=0, f(x) = f(0) = 0.  Since we have the inequality x<0, this means at the point (0, 0), the point will be open and not filled in.
