1. The sum of continuous functions is a continuous function. For example, let f(x)=x2+3x−4 and g(x)=2x+5. The sum of those two functions is a continuous function: f(x)+g(x)=x2+5x+1. The green dotted function represents f(x), the blue dotted function represents g(x), ...
And so the function is not continuous.But:Example: How about the absolute value piecewise function: At x=0 it has a very pointy change! But it is still defined at x=0, because f(0)=0 (so no "hole"), And the limit as you approach x=0 (from either side) is also 0 (so no ...
Answer: The relation between a and b is 4a - 4b = 11. Practice Questions on Continuous Functions Q. 1 Which of the following are true in case of a continuous function f(x) which is continuous at x = a. Check all that apply. Responses limₓ → ₐ f(x) exists limₓ → ₐ...
we will study the existence of a vector space of continuous functions f : Z(p) -> Q(p), where Z(p) and Q(p) are, respectively, the ring of p-adic integers and the field of p-adic numbers, such that each nonzero function does not satisfy the Luzin (N) property and the dimens...
f(x) is not continuous at x = 1. In lessons on continuous functions, such problems (logical jokes?) tend to be common. They are constructed to test the student's understanding of the definition of continuity. Such functions have a very brief lifetime however. After the lesson on ...
Pasting continuous functions with their domains on patches of closed sets which cover the whole domain. Comment: In the overlapping subdomain, the functions on different patches should be defined consistently. This condition is not required in “local formulation of continuity”, where the covering ...

f(x) = 1/x is not continuous as it is not defined at x=0. However, the function is continuous for the domain x>0. All polynomial functions are continuous functions. The trigonometric functions sin(x) and cos(x) arecontinuousand oscillate between the values -1 and 1. ...
The contrapositive of that statement is: if a function is not continuous then it is not differentiable. However, there are continuous functions that are not differentiable. What is the difference between differentiability and continuity of a function? The difference between differentiability and ...
