Math 233 Unit 2 Individual Project A computer virus is a malicious program that can cause high levels of destruction to your computer or your mobile...

I need to graph the following function and its derivative. I am using Desmos to accomplish this as I have much success in the past. But I am not certain of the notations to use.

the function is the number of computers infected in a given period of time in days, e.g. solve for t = 9

(S(t) = -9t^3 + At^2, 0 < t < 12 where  A =121 =

St = -9(t^3) + 121(t^2) = 3240 ... where t =9

and the derivative of St using

S't = d/dt (-9t^3 + 121t^2)

= S'9 = -27t^2 + 242t

=S'9 =-27(9)^2 + 242(9)

Now I do not know how to apply the proper notation and syntax into Desmos or Microsoft Mathmatics to produce the graph showing the trends in propagation of the virus.

I have attached the assignment for further clarification.
