Finding the value of x when y=-3

Question

Given the rational function f(x) = 6/x <(fraction)?

Choices:

1. x = 2
2. x = -18
3. x = 18
4. x = -2

Which one is correct?

Answer 1

If I understand your question correctly, x would be equal to -2.

If f(x) = -3, then -3 = 6 / x

Multiply both sides of the above equation by x, and you're left with -3x = 6.

Divide both sides of the equation by -3 to isolate x, and you're left with x = 6/-3 which is equivalent to -2.
