Final answer:
Based on the two conditions listed, k in terms of x can be expressed as either x + 1 or 1/x - 1, depending on the value of x.
Step-by-step explanation:
In the given question, we have two conditions:
One value of x is the + sign used in the numerator.
The other value of x is the - sign used in the numerator.
Based on these conditions, we can determine k in terms of x. Let's take the + sign first: If x is the + sign, then k = x + 1. Now, let's consider the - sign: If x is the - sign, then k = 1/x - 1.
In conclusion, k in terms of x can be expressed as either x + 1 or 1/x - 1, depending on the value of x.
