A. -3 < x < 1
b. x < = 4 or x > = 6
For this case we have the following vectors:

The dot product of two vectors is a scalar.
The point product consists of multiplying component by component and then adding the result of the multiplication of each component.
For the product point of the vectors a and b we have:
Answer:
The product point of the vectors a and b is:
your equation is linear, so there isn't any arch
