Any equation which maps each value of x in the domain to a value in the range is a function of x.

An equation is a function if it is in y=mx+b form or has a y= in foront of it. f(x) is a classic way of writing a function. Ex) X^2 is a function
A function is an equation (a relation) which has only one y-value for every x-value. If a single x-value has more than one y-value, the equation is no longer called a function.
No a linear equation are not the same as a linear function. The linear function is written as Ax+By=C. The linear equation is f{x}=m+b.
Y=x
In its normal form, you do not solve differential equation for x, but for a function of x, usually denoted by y = f(x).
