The idea of a function is that when you give it an input number, it will always give you a unique output number.
Examples:
y = 2x (y is a function of x)
h = 1/x2 + 5 (h is a function of x)
z = 23 + 3y - x + x/y (z is a function of x and y)
An equation simply tells you that two things are equal (left side is equal to the right side).
Examples:
y = 2x (note: also a function)
2x2 + 5 = 50 (not a function, but can be manipulated to become one: [x = squareroot of (50 - 5)/2])
2 + 19 = 21 (not a function)
All functions are equations, but not all equations are functions. Any equation where you have 1 input but more than 1 output is a relation. A function can have different inputs that give the same output, but not 1 input and multiple outputs (example: If you put 5 and -5 as inputs into the function y = x2, you will get the same output of 25.)

What is the difference between differentiation and a differential equation?
Differentiation: when you differentiate a function, you find a new function (the derivative) which expresses the old function's rate of change. For example, if f(x) = 2x, then the derivative f ' (x) = 2 for all x, because the function is always increasing by 2 units for every increase of x by 1 unit.A differential equation is an equation expressing a relationship between a named function and its derivatives. This can be as simple as y = y', where y is the original function and y' the derivative.
How do we differentiate between a quadratic equation and an exponential equation?
a quadratic equation must be in this form ax^2+bx+c=0 (can either be + or -) an exponential just means that the function grows at an exponential rate f(x)=x^2 or x^3

Differentiate a relation to a function?
A function is a special type of relation. So first let's see what a relation is. A relation is a diagram, equation, or list that defines a specific relationship between groups of elements. Now a function is a relation whose every input corresponds with a single output.

How do you find the slope with an equation?
You have to differentiate the equation. The dy/dx is the slope.

Is this equation a function y equals 3squared plus 2x minus 3 is this a function?
You can tell if an equation is a function if for any x value that you put into the function, you get only one y value. The equation you asked about is the equation of a line. It is a function.
