Point discontinuity is like a hole in the graph

True, Point of discontinuity is like a hole in the graph.

Step-by-step explanation:

As we know that if a graph has point of discontinuity then that point is represented as a hole in the graph.

Because at that point the continuity of the graph breaks and there that point becomes a hole for this reason.

Point of discontinuity can be of two forms :

1) Removal discontinuity - It is represented as a hole .

2) Non- removable discontinuity - It is represented as a jump.

Hence, Point of discontinuity is like a hole in the graph.

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)  

for a it would be 24 children.

for b i don't understand the question. is it saying for each individual person they pick 5 reds to 7 greens or is it the whole group. clarify and i hope this can you.
