Question
Consider the following ODE:
7x + 5x = 39(t)
x(0–) = 3
g(0–) = 0
a. Solve for x(t) using the Laplace transform method.
b. Use IVT to identify x(0+), and compare that with the initial condition x(0-). Identify if they are the same or not.
c. Plot x(t) from 0 < t< 10 s. and identify which value, x(0+) or x(0-), is represented by the plot of the function.
