To conduct an experiment, the room temperature in a lab needs to be as close a possible to 2 degrees Celsius. Any variation from this target temperature, whether warmer or cooler, is considered an error that could affect the experiment. Function 'v' gives the absolute temperature error as a function of the room temperature in degrees Celsius, 'x'.

Select ALL statements that are true about the function and the situation.

1) When the room temperature is 0 degrees Celsius, v(0) has a value of 2.
2) When the room temperature is -3 degrees Celsius, the absolute temperature error,
v(-3), is -1
3) When the room temperature is 3 degrees Celsius, v(3) is 5
4) The equation v(x) = Ix-2I gives us the absolute temperature error when the room temperature is x degrees Celsius.
5) When v(x) = 0.5, the room temperature could be -1.5 or -2.5 degrees Celsius
6) The equation v(x) = Ix+2I gives us the absolute temperature error when the room
temperature is x degrees Celsius.
