The graph shows a bacteria population as a function of the number of hours since an antibiotic was introduced.
what does the end behavior for x increasing without bound represent?
the bacteria population will approach, but never reach, 0.
the bacteria population will approach, but never reach, 1200.
the bacteria population will reach 1200.
the number of bacteria will approach, but never reach, 75.

The bacteria population will approach, but never reach, 0. Hope I helped :)

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
