Question

The temperature of a refrigerator is 38°F give or take 2º.

Answer 1

Using the absolute value function, we have that:

a. The equation is: |x - 38| = 2.

b. The minimum temperature is of 36 ºF and the maximum temperature is of 40 ºF.

What is the absolute value function?

The absolute function is defined by:

• |x| = x, x ≥ 0.

• |x| = -x, x < 0.

It measures the distance of a point x to the origin.

For this problem, the difference between the the temperature and 38 ºF can be of at most 2 ºF, hence the absolute value equation is:

|x - 38| = 2.

The minimum and maximum temperatures, in ºF, are given, respectively, by:

• x - 38 = -2 -> x = 36.

• x - 38 = 2 -> x = 40.
