Answer:
The range is {-4, 0, 28}
Step-by-step explanation:
Domain reffers to input values, or x-coordinates.
Put the domain values into the function to solve for the y-coordinates, which is the range.
y = 4(2) - 12
y = 8 - 12
y = -4 ... (2, -4)
y = 4(3) - 12
y = 12 - 12
y = 0 ... (3, 0)
y = 4(10) - 12
y = 40 - 12
y = 28 ... (10, 28)
