A function tries to define these relationsips. It tries to give the relationship a mathematical form. An equation is a mathematical way of looking at the relationship between concepts or items. These concepts or items ar represented by what are called variables.
The solution is the answer to an equation.
In a periodic equation a triangle can be used to represent the given change of something.
Without an equality sign the information given does not represent an equation.
Nothing. There is no l in the equation.
You just have to follow the rule of quadratic functions. Example y = mx+b is the rule for linear functions. ax^2+bx+c is the rule of quadratic equation.

You cannot represent a proportional relationship using an equation.

Coefficients in a chemical equation represent the number of units of the formula immediately following the coefficient that are involved in the balanced equation for the reaction.
interest
b is the negative sum of the roots of the equation
Nothing. There is no l in the equation.
The (unknown) x (I suppose that's what you mean) is a variable. It's commonly used to represent any number. For example if you have the equation 3x+2=5, x represents the number which will verify the equation. x can be used with equations, functions etc.
You just have to follow the rule of quadratic functions. Example y = mx+b is the rule for linear functions. ax^2+bx+c is the rule of quadratic equation.
The equation x=c where c is a constant is the equation of a vertical line. It can't be a function but it is linear so the answer is no. For example, the vertical line produced by the linear equation x = 3 does not represent a function. We cannot write this equation so that y is a function of x because the only x-value is 3 and this "maps" to every real-number y.
