To conduct an experiment, the room temperature in a lab needs to be as close as possible to -4 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.

When the room temperature is 0 degrees Celsius, v(0) has a value of 4.

When the room temperature is -5 degrees Celsius, the absolute temperature error, v(-5), is -1.

When the room temperature is 1 degree Celsius, v(1) is 5.

The equation v(x) = |x + 4| gives us the absolute temperature error when the room is x degrees Celsius.

When v(x) = 0.5, the room temperature could be -3.5 or -4.5 degrees Celsius.
