Find limit as x approaches 4 from the left of the quotient of the absolute value of the quantity x minus 4, and the quantity x minus 4 . You must show your work or explain your work in words.

See below for the mathematical form of the equation.

this is fun

one way is to aproximate by getting values closer and closer to the value
the small negative sign on the top left of the 4 means we need to aproximate from the left, or from values less than 4 to 4

so like using 3.9, 3.99. 3.999, etc

if we did 3.9, we get 0.1/-0.1=-1
if we did 3.99, we get 0.01/-0.01=-1
if we did 3.999, we get 0.001/-0.001=-1
I notice a pattern

so therefor I say the limit as x approaches 4 from the left is -1

Answer:

-1

Step-by-step explanation:

Given,

[tex]lim_{x\rightarrow 4^{-}} \frac{|x-4|}{x-4}[/tex]

Let h represents a small change,

So, we can write,

[tex]lim_{x\rightarrow 4-h} \frac{|x-4|}{x-4}[/tex]

[tex]=\frac{|4-h-4|}{4-h-4}[/tex]

[tex]=\frac{|-h|}{-h}[/tex]

[tex]=\frac{h}{-h}[/tex]

[tex]=-1[/tex]

Hence, the value of the given limit is -1.
