Question

#4 which input is not allowed?

Answer 1

Answer:

x = -2

Step-by-step explanation:

Since we cannot divide by 0, the value of x which results in a denominator that is 0 is a value excluded from the domain;

This value can be found by setting the denominator equal to 0;

In this case, the denominator is -5x - 10 so we construct the following equation and solve;

-5x - 10 = 0

5x = -10

x = -2

Answer 2

Step-by-step explanation:

-5x-10≠ 0

-5x≠ 10

x≠ -2

-2 is not allowed i.e option A
