Use the graph shown with three pieces and endpoints at x = 0 and x = 3. Which piecewise definition matches the graph?
A
f(x) = 2x + 1 for x <= 0; f(x) = -2 for 0 < x < 3; f(x) = x - 5 for x >= 3
B
f(x) = 2x + 1 for x < 0; f(x) = -2 for 0 <= x <= 3; f(x) = x - 5 for x > 3
C
f(x) = -2 for x <= 0; f(x) = 2x + 1 for 0 < x < 3; f(x) = x - 5 for x >= 3
D
f(x) = 2x - 1 for x <= 0; f(x) = -2 for 0 < x < 3; f(x) = x + 5 for x >= 3
