Answer:
Excluded values are any given number(s) that can make an expression's denominator zero.
First you set the denominator equal to zero, like so:
(x-1)(x+7) = 0
Now you can see if you make each (x-1) and (x+7) equal to zero:
x-1=0 x=1
x+7= x=-7
Excluded values:
From my understanding 1 and -7 would be the excluded values.
