To conduct an experiment, the room temperature in a lab needs to be as close as 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.

A) The equation v(x)=|x+2| gives us the absolute temperature error when the room temperature is degrees Celsius.
B)When v(x) = 0.5, the room temperature could be -1.5 or -2.5 degrees Celsius.
C)The equation v(x)=|x−2| gives us the absolute temperature error when the room temperature is x degrees Celsius.
D)When the room temperature is -3 degrees Celsius, the absolute temperature error, v(-3), is -1.
E)When the room temperature is 0 degrees Celsius, v(0) has a value of 2.
F)When the room temperature is 3 degrees Celsius, v(3) is 5.
