The function c(h)=(2h^2+5h)/(h^3+8) models the concentration of a medication in the bloodstream (as a percent), hours (h) after its injection into muscle tissue. a) suppose you need to readminister this injection at the point when the concentration is less than 0.5%. if the first injection was given at 8: 00 am, what time should the next injection be given?

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
