Open Dot or Closed Dot?
Difficulty: Easy · Topics: Algebra, Functions, Graphs of Functions
Bo‘sh nuqtami yoki to‘ldirilgan nuqtami?
The graph of y=f(x) has a jump at x=2. An open dot means the point is not on the graph.
graph "x":[-3,5],"y":[-2,5],"xTicks":[-3,-2,-1,1,2,3,4,5],"yTicks":[-2,-1,1,2,3,4,5],"grid":true,"clip":true,"label":"Two rays with a jump at x = 2","items":["type":"line","from":[-3,-1],"to":[2,4],"start":"arrow","end":"open","type":"line","from":[2,1],"to":[5,4],"start":"closed","end":"arrow","type":"guide","at":[2,4],"to":"both","type":"guide","at":[2,1],"to":"y","type":"label","at":[-1.6,1.6],"text":"y = f(x)","size":13]
Find f(-1)+f(2)+f(4).
y=f(x) ning grafigi x=2 da sakraydi. Bo‘sh nuqta shu nuqta grafikka tegishli emas ligini bildiradi.

f(-1)+f(2)+f(4) ni toping.
