Question

The graph of a piecewise function is shown.

The graph shows a piecewise function in 3 pieces. The first piece is curved and increasing from the left through negative 3 comma negative 7 and ends at a closed point negative 2 comma negative 2. The second piece is linear with an open point at negative 2 comma negative 1 and another endpoint at 2 comma 1. The third piece is curved with an endpoint at 2 comma 1, and it goes through the point 3 comma 6 and continues to increase to the right.

What is the domain of the function?

(−∞,∞)
[−∞,∞]
(−∞,0)
(0,∞)

Answer 1

answer is a and b
