Answer:

Option D. 8

Step-by-step explanation:

we have

[tex]f(x)=\frac{x^{2}-16 }{x-4}[/tex]

Remember that

[tex]x^{2}-16 =(x+4)(x-4)[/tex]

substitute

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

Remove the discontinuity at x=4

Simplify

[tex]f(x)=(x+4)[/tex]

so

Find the value of f(4)

For x=4

[tex]f(4)=(4+4)=8[/tex]
