HELP I DONT UNDERSTAND PLSS HELP :(

D

Step-by-step explanation:

The range of a graph is the span of y-values it covers.

From the graph, we can see that the span of y-values covered goes from y=-3 all the way to y=3.

However, note that at y=-3, while it is a closed circle, it is an open circle at y=3.

This means that we do not include y=3 in our range, but we do include y=-3 in our range.

So, our range is all values between -3 and 3 including -3.

In set notation, this is (and remember since this is the range, to use y):

So, our answer is D.

And we're done!

d

step-by-step explanation:

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.
