Question

Urgent help needed Pls Help

Answer 1

Do u understand the concept of continuity?

Answer 2

Not completely @ allank

Answer 3

Okay. Lemme walk u through it..

Answer 4

@allank

Answer 5

If we have the graph of a function, it is continuous if it is differentiable at all points i.e. it has no breaks, sharp corners, etc.

Answer 6

if lim of f(x) as x approaches a from the left = the limit as x approaches a from the right, the limit exists.

if the limit exists at a, then the function is continuous at a.


[square brackets] mean that the number is included in the interval
(round brackets) mean that the point is not included in the interval.

Answer 7

[-4,2),(-2,2),[2,4),(4,6),(6,8)

Answer 8

Carry on @Euler271

Answer 9

@allank so when u say sharp corners do you also mean by turning points where it slowly rises and then falls

Answer 10

No, the function is differentiable there.
