Answer:

(g\circ h)(x)=-x^2-x-3

Step-by-step explanation:

So we have the two functions:

g(x)=-x-3\text{ and } h(x)=x^2+x

And we want to find:

(g\circ h)(x)

This is the same thing as:

=g(h(x))

So, substitute h(x) into g(x):

g(x)=-x-3\\g(h(x))=-(x^2+x)-3

Distribute the negative:

g(h(x))=-x^2-x-3

And we're done!

So:

(g\circ h)(x)=-x^2-x-3

harkovskaia [24]
Let us assume the initial number of bacteria in the culture = xAfter 1 hour,The number of bacteria = 185x/100                                      = 1.85xAfter 2 hours,The number of bacteria = (185 * 1.85x)/100                                       = 3.42xSo3.42x = 12500x = 12500/3.42   = 3654.97   = 3655From the above deduction, we can conclude that the initial number of bacteria in the culture is 3655.
