Respuesta :

x^2 - 16
--------
4x + 24


when x = -6 the denominator 4x+24 = 0   so there is a discontinuity at x = -6

This is a vertical asymptote x = -6

There is also a sloping asymptote  - you find this by getting the quotient 
which is y = 0.25x - 1.5  This is the equation of this asymptote.

Answer:

x= -6 is the point of discontinuity.

Step-by-step explanation:

We have been given the expression

[tex]\frac{x^2-16}{4x+24}[/tex]

The first thing to find the discontinuity is to factorize the given rational function:

After factorization  we get:

We will use [tex]a^2-b^2=(a+b)(a-b)[/tex]

[tex]here, a=x\text{and}b=4[/tex] we will get:

[tex](x+4)(x-4)=x^2-4^2[/tex]

we will get:

[tex]\frac{(x+4)(x-4)}{4(x+6)}[/tex]

Discontinuity is the point where value of the function becomes not defined

Here, the point of discontinuity is -6 because when denominator becomes zero. function becomes not defined.

It has vertical asymptote but function is not defined.

Hence it is the point of discontinuity.
