A: Given:

Q: y = C¡e e-2= + Cze³* + C2e%

A:

Q: Y = C1e* + C2ex + C3e2x where y(0) -D 0, y (0) %— 1, у"(0) — 2

A: The differential equation is: y=c1e-x+c2ex+c3e2x At x =0, y = 0, so c1+c2+c3=0....(1) At x = 0,…

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
