Limit (x approach -4) of | x+4 |
*thats absolute value of x+4.
can you show me the steps please!
THANKS

the limit approaches 0 from both sides. the graph will look like a V, as all absolute value graphs do.

There are no real steps, we can see as x gets closer and closer to -4 the value between the absolute brackets gets closer and closer to zero.
and the | 0 | is still 0.

y = x + 4
y + Ïy = x + Ïx + 4
Now Subtract y = x + 4
y + Ïy - y = x + Ïx + 4 - x - 4
Ïy = δx
Ïy / δx = 0
If δx â - 4, then Ïy / δx â dy / dx â - 4
If y = x + 4, then dy / dx = 0
