[4 Pts. Use the definition of continuity to show that the function f is continuous at <=0 10 g(x)= 3-4
9. Prove that the function f(x) = ax+b is uniformly continuous on R by directly applying the e, 8 definition of uniform continuity.
Format requirement: Question 3. E-6 Proof (Show Working) 10 points 249 Show that f:RR defined by f(x) is continuous at x = 7 using only r +3 cosa the epsilon-delta definition of continuity. Note that we want you to do it the hard way: you are not allowed to use the limit laws or the combination of continuous functions theorem or similar. You must give an 'e-δ style proof Solution: Let ε > 0 be given and choose δ =...
Please Answer 135 Below Completely: Definition Let E-R and f : E-+ R be a function. For some p E E' we say that f is continuous at p if for any ε > 0, there exists a δ > 0 (which depends on ε) such that for any x E E with |x-Pl < δ we have If(x) -f(p)le KE. This is often called the rigorous δ-ε definition of continuity. A couple of things to note about this definition....

Use the definition of uniform continuity to prove that f(x)is uniformly continuous on , 00
definition of continuity to prove that f : (0,00) by f(x)-13 + 1 is continuous at every Zo 0. Use the є-ð definition ) Use the є- R defined that g(x)-_a_ is continuous at every a є (-1,00) +1
7. Using the definition of continuity directly to prove that f: (1,00) + R defined by f(3) = and f(1) = 0 is continuous on at 2 = 2 but not continuous at 1.
Advanced Calculus (3) Let the function f(x) 0 if x Z, but for n e z we have f(n) . Prove that for any interval [a3] the function f is integrable and Ja far-б. Hint: let k be the number of integers in the interval. You can either induct on k or prove integrability directly from the definition or the box-sum criterion. (3) Let the function f(x) 0 if x Z, but for n e z we have f(n) ....
We used definition of homeomorphic as follows. If X and Y are topological spaces, a function f: X to Y is called homeomorphism if 1. f is continuous 2. f is bijective 3. inverse of f is continuous And in this case, we say that X is homeomorphic with Y. Thank you ! infinite) (5) Prove that all semiopen intervals in R (finite or homeomorphic are infinite) (5) Prove that all semiopen intervals in R (finite or homeomorphic are
