k%28x%29=4x-16 Start with the given equation.


4x-16%3E0 Set the right side greater than zero.


4x%3E0%2B16 Add 16 to both sides.


4x%3E16 Combine like terms on the right side.


x%3E%2816%29%2F%284%29 Divide both sides by 4 to isolate x.


x%3E4 Reduce.

Answer:

So the answer is x%3E4 which means that any value of x that is greater than 4 will make k%28x%29 greater than zero.
