Answer:
Option A
Explanation:
Answer: Option A
Piecewise function is defined by different function over different intervals.
In this case, y = x + 3 when x is less than 0 (if x is negative).
y = 2x when x is greater than or equal to 0.
When x = -1, y = x + 3.
y = -1 + 3 = 2 (-1,2)
When x = -2, y = x +3
y = -2 + 3 = 1 (-2,1)
(0,3) is not a solution of the piecewise function. So, it is marked with a open dot.
This function is marked in the graph with red color.
When x ≥ 0 , y = 2x
So, for x = 0, y = 2*0 = 0 (0,0)
For x = 1 , y = 2*1 = 2 (1,2)
For x = 2, y = 2*2 = 4 (2,4)
(0,0) is a solution and so, it is marked with a solid dot.
This function is marked in the graph with blue color.
