a. x= 0
b. x= -64
c. x= -16
d. x= -8

Answer 1

The excluded value is -16
C

Answer 2

Option C is correct.

Explanation:

Given Function is
`y=(3)/(4x+64)`

We have to find values which is excluded from the function.

We know that Values are excluded where function doesn't exist.

Given function is rational function.

So, Values excluded where denominator equals to 0.

⇒ 4x + 64 = 0

4x = -64

x = -16

Therefore, Option C is correct.
