Question

What are the excluded values?

Answer 1

Answer:

Option (c) is correct.

The values that are excluded for the given expression $\frac{x-7}{x+9}$  is -9 .      

Step-by-step explanation:

Given: Expression $\frac{x-7}{x+9}$

We have to find the values that are excluded for the given expression $\frac{x-7}{x+9}$                

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

Consider the given expression  $\frac{x-7}{x+9}$

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 $\frac{x-7}{x+9}$  is -9 .
