Let the set t be given by t = { x in the reals | x^2 < 2}. describe maximum, minimum, supremum (least upper bound), and infimum (greatest lower bound) for t (they may not exist).

Step-by-step explanation:

We have the set . Now, let us recall that , and the inequality is equivalent to , so our set can be written as

.

The inequality is equivalent to . So,

. Thus, .

Now, we have that is the open interval (-2,2). From this we can extract all the information we need:

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.
