Determine the domain of the following graph:

x is greater than or equal to -7 but less than 9.

Step-by-step explanation:

Find the lowest and higest points on the graph.

Remember the domain is on the x - axis.

The lowest point on the graph is -7, but the dot is filled in so it must be equal to it.

The next step is that the graph is getting larger so it is greater than or equal to.

On the other side of the graph do the same but it is less than not equal because the dot is open.

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
