If f(x) = 3x2 - 2x + 7 and g(x) = x - 4, find and simplify the composite function (f ∘ g)(x).
(f ∘ g)(x) = 3x2 - 26 + 63
(f ∘ g)(x) = 3x2 - 26 - 63
(f ∘ g)(x) = 3x2 + 26 + 63
(f ∘ g)(x) = 3x2 + 26 - 63

Aljoe and his friend are playing a number - guessing game. Aljoe asks his friend to think a positive number, then add four to the number. Next, square the resulting number, and multiply the result by 3. Finally, divide the result by 2. If you are his friend and you get a result of 50, (a) write an inverse function that will give you the original number and (b) determine the original number.
f −1(x) =√x/2 − 3; original number is 2
f −1(x)=√x/3 − 3; original number is 3
f −1(x) =√x/4 − 3; original number is 4
f −1(x) =√x/5 − 3; original number is 5
1. COVID-19 pandemic according to news is spreading rapidly, transferring from human to human. It is a kind of virus that affects the human respiratory system and it is commonly associated with cough, pneumonia, SARS (Severe Acute Respiratory Syndrome), and other respiratory-related infections. Let us assume that the virus has an initial population of 10,000 and grows to 25,000 after 50 minutes. Assume that its growth follows an exponential model f(t) = Aekt representing the number of viruses after t minutes. The e is used in the model because the virus continuously grows over time.
a. Find A and k.
b. Use the model to determine the number of viruses after 6 hours.
A=-15, 000, k=0.08132, viruses after 6 hrs is 7,513,257
A=-12, 000, k=0.01823, viruses after 6 hrs is 7,315,257
A=-10, 000, k=0.01832, viruses after 6 hrs is 7,315,752
A=-8, 000, k=0.1832 , viruses after 6 hrs is 7,513,752
