In mathematics, a function is a binary relation between two sets that associates each element of the first set to exactly one element of the second set Typical examples are functions from integers to integers, or from the real numbers to real numbers Functions were originally the idealization of how a varying quantity depends on another quantity265 · Section 56 Conservative Vector Fields For problems 1 – 3 determine if the vector field is conservative For problems 4 – 7 find the potential function for the vector field ( 1 2 y)) j → Solution Evaluate ∫ C →F ⋅d→r ∫ C F → ⋅ d r → where →F (x,y) = (2yexy 2xex2−y2) →i (2xexy −2yex2−y2)→j F → ( x, yExplanation First, input the function of h into g So f(x) = 4(25πx 5) – 3, then simplify this expression f(x) = πx – 3 (leave in terms of π since our answers are in terms of π)Then plug in 1 for x to get π 17

A function may be thought of as a rule which takes each member x of a set and assigns, or maps it to the same value y known at its image x → Function → y A letter such as f, g or h is often used to stand for a functionThe Function which squares a number and adds on a 3, can be written as f(x) = x 2 5The same notion may also be used to show how a function affects particular values1 In fact this belongs to a functional equation of the form http//eqworldipmnetru/en/solutions/fe/fe12pdf Let { x = u ( t) f = u ( t 1) , Then u ( t 2) = u ( t 1) u ( t) u ( t 2) − u ( t 1) − u ( t) = 0 u ( t) = C 1 ( t) ( 1 5 2) t C 2 ( t) ( 1 − 5 2) t , where C 1 ( t) and C 2 ( t) are arbitrary periodic functions withFX Math Junior send the problem text, typed in by user, to the cloud problem solving server, managed by Euclidus IncAnd the problem solving server use the user typedin problem text only to derive the answer and solution of the problem for user

Edit As pointed out in the comment section, this equation has infinitely many solutions mathf(x)=x/math is a trivial solution Examples * mathf(x)=kx/mathThis means that the function is injective Since\( f(f(0))=f(0)0=f(0) \), because of injectivity we must have \( f(0)=0 \), implying\( f(f(0))=0 \) If there were another \( x \) such that \( f(f(x))=0=f(f(0)) \),injectivity would imply \( f(x)=f(0) \) and\( x=0 \) Problem 4Given f (x) = x2 2x – 1, evaluate f (§) Well, evaluating a function means plugging whatever they gave me in for the argument in the formula This means that I have to plug this character " § " in for every instance of x Here goes f (§) = (§) 2 2 (§) – 1 = § 2 2§ – 1
