Write four numbers that could be ordered between these numbers 59 through 1,000

the answer is (b) bounded below.

step-by-step explanation:

y=2^x.

we are to state whether the function is bounded above, bounded above or bounded.

we have -  

if~x=-\infty,~\textup{then}~y=2^x=2^{-\infty}=\dfrac{1}{2^\infty}=0,

and

[tex]if~x=\infty,~\textup{then}~y=2^x=2^{\infty}=\infty.

therefore, the range of the given function will be [0,∞).

thus, the given function is bounded below but not bounded above.
