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

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

We set the denominator,which is x2, to 0(x2=0, which is x=2) When we set the denominator of g(x) equal to 0, we get x=0Similar Problems from Web Search Assuming that f is integrable on compact sets, if f (x) = \int_0^x f (t) dt, then f' (x) = f (x), and f (0) = 0 The (unique) solution is f (x) = f (0) e^x, hence f (x) = 0 for all x As an f (t)dt, then f ′(x) = f (x), and f (0) = 0If x = 3 then f(x) = f(3) = 1/3 2 = 1/9 If x = 3 5 then f(x) = f(3 5) = 1/(3 5) 2 = 1/8 2 = 1/64 If x = 3 h then f(x) = f(3 h) = 1/(3 h) 2 I hope now you see that f(x h) = 1/(x h) 2 Thus for b, Write the two fractions with a common denominator and then simplify the numerator Write back and tell me what you got, Harley
