Hello from MrBillDoesMath!

Answer:

Domain:  x >=0 for both cases


Discussion:

Assuming we are dealing with real valued functions, the domain of

y = x^(1/2) +4

is the set of all "x" such that x>= 0  (so we are taking the square root of a positive, or zero, real number)


The domain of  x^(1/2) +6 -7 is the same as for the last function  and for the same reason.


Thank you,

MrB

Rus_ich [418]

Answer:

The Bison is faster by 10 mph.

In 1 minute, the bison runs 3, 520 feet .

In 60 minutes, the bison would run  3520*60 feet  = 211, 200 feet per hour.

These are equivalent to 40 miles per hour since 1 mile is equivalent to 5, 280 feet. Hope this helps! ^-^
