Answer:
16
Step-by-step explanation:
To solve this, you need to evaluate the function at f(1), which just means that you have to plug in 1 for any x you see in the equation. For example, here f(1) = 2(1) + 2 which simplifies to 4. Next find f(5). By doing the same process you will find that this is 12. The problem asks for f(1) + f(5) so by putting those values in you will get 4+12=16. Hope this helps! :)
Answer:
Step-by-step explanation:
Given: .
we need to find the correct form for if the equation is solve using undetermined coefficients.
A first order differential equation is said to be homogeneous if for all t.
Consider homogeneous equation
Let be the solution .
We get
Since , .
So, we get solution as
As constant term and are already in the R.H.S of equation
, we can take as
