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 values.

G(x) and f(x) are inverse functions if g(f(x)) = x and f(g(x)) = x So, algebraically, it's pretty straightforward #f(g(x)) = 1/(1 (1 x)/x)#.

The equation in your question actually defines two different functions One, which could be expressed explicitly is the trivial one, namely y=x, and along that one the answer to your question is clearly y’=1. 4104 Use antidifferentiation to solve simple initialvalue problems. Solve the vibrating string problem with L = c = 1, f(x) = x(1−x) and g(x) = 1−x We first find f∗(x) The odd extension of f to −1,1 is f 1(x) = x(x 1) if −1 ≤ x.

And we see that f(x)/g(x) tends to 1 as x tends to ∞ 1 2 STEVEN J MILLER Note you could also do Problem 3 by expanding out the expressions, but that is much harder For example, f(x)g(x) is a polynomial of degree 4 that can be analyzed directly Also, for f(x)/g(x) one could proceed by L’Hopital’s rule. 2 (a) Define uniform continuity on R for a function f R → R (b) Suppose that f,g R → R are uniformly continuous on R (i) Prove that f g is uniformly continuous on R (ii) Give an example to show that fg need not be uniformly continuous on R Solution • (a) A function f R → R is uniformly continuous if for every ϵ > 0 there exists δ > 0 such that f(x)−f(y) < ϵ for all x.

G(x) = L Recall last day, we saw that lim x!0 sin(1=x) does not exist because of how the function oscillates near x = 0 However we can see from the graph below and the above theorem that lim x!0 x 2 sin(1=x) = 0, since the graph of the function is sandwiched between y = x2 and y= x2 O x K 1 K 05 0 05 1 K 1. 12 2 Limits of Functions We can rephrase the ϵδ definition of limits in terms of neighborhoods Recall from Definition 116 that a set V ⊂ R is a neighborhood of c ∈ R if V ⊃ (c−δ,cδ) for some δ > 0, and (c − δ,c δ) is called a δneighborhood of cA set U is a punctured (or deleted) neighborhood of c if U ⊃ (c−δ,c)∪(c,cδ) for some δ > 0, and (c − δ,c.
