Question 334628: Consider the functions f(x)=2x-8 and g(x)=-x^2=3. Find the x-coordinate(s) of the points of intersection of f(x) and g(x). Answer by solver91311(24713) (Show Source):
I'm pretty sure you have a typo in your definition of . Taking what you wrote literally, is a Boolean function that is always false.
Since is always positive, must always be negative, and is an unwaveringly false statement since 3 is a positive number.
Such a function does not have a value that exists in , hence there is no point in to which maps. Therefore there is no point of intersection between and .
