Step-by-step explanation:
The excluded values are any values of x that make the function undefined
Given
![\frac{1}{(x+4)(x-2)(x-5)}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%28x%2B4%29%28x-2%29%28x-5%29%7D)
The denominator of the rational function cannot be zero as this would make it undefined. Equating the denominator to zero and solving gives the values that x cannot be.
(x + 4)(x - 2)(x - 5) = 0
Equate each factor to zero and solve for x
x + 4 = 0 ⇒ x = - 4
x - 2 = 0 ⇒ x = 2
x - 5 = 0 ⇒ x = 5
x = - 4, x = 2, x = 5 are the excluded values
