1353. Question or Comment:
Suppose that the function f is defined, for all real numbers, as follows.
f(x) = {x - 2 if x < -2
{ 3x + 2 if x ≥ -2
Graph the function f. Then determine whether or not the function is continuous.

Replied by Admin : We can see from this graph, it is continuous function but we can only say that it is continuous, when left lim= right lim = functional value at that point. Thank you.

Graph the piecewise function below by dragging the endpoints of the lines to the correct locations, then select whether the endpoints are included in the graph or not.

Replied by Admin : Type
-x+1 where x<-2
-(x^2) where -2<=x<1
x-3 where x>=1
Then you get the graph. Thank you very much.

Dear admin, how can i write x to the power 3 ?

Replied by Admin : You can write x^3 or x**3
Thank you.
