The correct piecewise function for the given points is:
y = -2, x > 2
y = 3, x <= -3
y = -5, -3 < x <= -5
y = -6, -5 < x <= -6
y = -9, -6 < x <= -9
y = -2x, -9 < x <= -8
y = -3x, -8 < x <= -7
y = -4x, -7 < x <= -6
y = -5, -6 < x <= -5
y = -4, -5 < x <= -4
y = -3, -4 < x <= -3
y = -2, -3 < x <= -2
y = -1, -2 < x <= -1
y = 0, -1 < x <= 0
y = 1, 0 < x <= 1
y = 2, 1 < x <= 2
y = 3x, x > 2
y = -2x, x > 0
y = 3, x <= 0
A. Y = { -2, x > 2
3, x <= 3
B. Y = { -2x
3x
C. Y = { -2x, x < 0
3, x > 0
D. Y = { -2, x < 0
3, x >= 0
The correct answer is:
C. Y = { -2x, x < 0
3, x >= 0
