The complete question is
"Find the general solution of the given differential equation
y''-y=0, y1(t)=e^t , y2(t)=cosht
The function
is the solution of the given differential equation.
The function y(t)=cosht is the solution of given differential equation.
<h3>What is a function?</h3>
The function is a type of relation, or rule, that maps one input to specific single output.
Given;

Given differential equations are,
y''-y = 0
So that,
Substitute values in the given differential equation.

Therefore, the function
is the solution of the given differential equation.
Another function;
So that,

Hence, function y(t)=cosht is solution of given differential equation.
