Question

What are the excluded values of the function? (look at comments)

Answer 1

y=3\[y=\frac{ 3 }{ 4x+64 }\]

Answer 2

The excluded values would be when the denominator is equal to 0

So solve this:
\(\sf 4x+64=0\)

And whatever x equals is the excluded value :)

Answer 3

The reason that the denominator equals 0 is because then the function will be undefined.

Answer 4

Oh ok that makes sense thx :)

Answer 5
