The document discusses whether relations define y as a function of x and what the domains are. The first relation y = x + 1/11 is not a function, and has a domain of (-infinity, 11) U (11, infinity). The second relation 6x - 2y < -8 is not a function, with a domain of (-infinity, infinity).

1. Determine whether the relation defines y as a function of x. Give the domain. y = x + 1/11 Not
a function; domain (-infinity, 11) u (11, infinity) Function; domain (-infinity, -1) u (-1, infinity)
Not a function; domain: (-infinity, infinity) Function; domain: (-infinity, infinity) Determine
whether the relation defines y as a function of x. Give the domain. 6x - 2y
Solution
y = (x+1)/11
Linear equation : It is a function with domain ( -inf , inf )
Option D
6x -2y < -8
A function requires a unique y value for each x value.
An inequality allows for multiple solutions, so you have multiple y values for a given x value so
it's not a function.
It is not a function Domain (-inf , inf)
