If f (x+y)=f (x)+f (y) and f (x.y)=f (x)f (y) then f (x)=x , x in R. I think it is fine to use that definition of equality of numbers. As for the proof, it looks good to me. Good job!I'm not sure what you mean by "definition of equality of two numbers". Could you clarify or provide the definition?13.10E: Exercises for Lagrange Multipliers. In exercises 1-15, use the method of Lagrange multipliers to find the maximum and minimum values of the function subject to the given constraint. 1) Objective function: f(x, y) = 4xy f ( x, y) = 4 x y Constraint: x2 9 + y2 16 = 1 x 2 9 + y 2 16 = 1.WebOn the graph of a line, the slope is a constant. The tangent line is just the line itself. So f' would just be a horizontal line. For instance, if f (x) = 5x + 1, then the slope is just 5 everywhere, so f' (x) = 5. Then f'' (x) is the slope of a horizontal line--which is 0. So f'' (x) = 0. See if you can guess what the third derivative is, or ...Consider the above figure where y = f(x) is a curve with two points A (x, f(x)) and B (x + h, f(x + h)) on it. Let us find the slope of the secant line AB using the slope formula. For this assume that A (x, f(x)) = (x₁, y₁) and B (x + h, f(x + h)) = (x₂, y₂). Then the slope of the secant line AB is,Web7 x’ + y’ + z’ f(x y z) = (x+y+z)(x+y’+z)(x’+y’+z’) The 0’s of the Truth Table show the maxterms that are in the Canonical POS expression Maxterm List Form: f(x y z) = ΠM(0,3,6) Note the differences from the way minterms are complemented

The Function which squares a number and adds on a 3, can be written as f (x) = x2+ 5. The same notion may also be used to show how a function affects particular values. Example. f (4) = 4 2 + 5 =21, f (-10) = (-10) 2 +5 = 105 or alternatively f: x → x2 + 5. The phrase "y is a function of x" means that the value of y depends upon the value of ...f(x) = 1 f ( x) = 1. f(x) = 0 f ( x) = 0. However, these solutions are family solutions of f(x) =xn f ( x) = x n. What I meant by this is that, when n = 1 n = 1 you get the function f(x) = x f ( x) = x. When n = 0 n = 0 you get f(x) = 1 f ( x) = 1 and when x = 0 x = 0 well you get f(x) = 0 f ( x) = 0 . So, it seems f(x) =xn f ( x) = x n is the ...

Cauchy's functional equation is the functional equation : A function that solves this equation is called an additive function.
