Is the function graphed at right continuous at the following values of ? If not, explain which conditions of continuity fail. Homework Help ✎

and

Use the three conditions to test if the function is continuous at and

*.*

Examine the graph at .

Condition 1:

Condition 2:

*f*(-4) = 0.

Therefore *f*(−4) exists.

Condition 3:

The function is continuous at *x* = −4.
