Answer:

Option (c) is correct.

The values that are excluded for the given expression
(x-7)/(x+9) is -9 .

Explanation:

Given: Expression
(x-7)/(x+9)

We have to find the values that are excluded for the given expression
(x-7)/(x+9)

For rational numbers , we exclude those values for which the denominator of the rational expression is 0.

Consider the given expression
(x-7)/(x+9)

Denominator of the given expression is x + 9

Put x+ 9 = 0

We have x = - 9

Thus, The values that are excluded for the given expression
(x-7)/(x+9) is -9 .
