The domain is defined as all the possible x values. The graph extends to the left and to the right without bounds so the domain is All Real Values of x.
It can also be written as (-∞, ∞) This is called interval notation.

Note that the minimum value of f(x) is -4 so the range is [-4, ∞). (All real values of y equal to or greater than -4)

A cheetah ran 275 feet in 3.23 seconds. How fast did the cheetah run in miles per hour? Round your answer to the nearest whole m

yawa3891 [41]

First we convert feet into meters, since 1 feet is 0.3048 m: 275 feet * 0.3048 = 83.82m.

Then we do: 83.82m / 3.23s = 25.9504644 m/s.

Then we convert that into miles per hour by 2.23694, so we do:

25.9504644 * 2.23694 = 58.0496318.

Then we round it to 58 mph.

So the answer is: The cheetah was running at 58 mph.
