Answer:
A) (-2,2) lies on both lines
Step-by-step explanation:
Can be both, because if all three were negative, it would be
negative*negative= positive
positive*negative=negative
example: -1*-1*-1=-1
but if all three were positive, it would obviously be positive, because any number of positives can't make negatives in multiplication.
The correct option is D. In fact, you can evaluate this function at every possible input x.
All this function does is:
- Take a number x
- Add 6
- If the result is negative switch the sign, otherwise keep it as it is
As you can see, you can perform these operations regardless of the input x.
