help please!!
will medal :))
Take note of the arrows. They indicate that the line stretches on in both directions and does so infinitely. So the line goes on forever So the range would be the set of all real numbers BUT there's a hole on the line (hopefully you're able to see it?)
so its all real numbers?
if the hole wasn't there yes, but there's a hole
do you see where the hole is at? it's on the line
thank you!
the answer isn't "all real numbers" again, there's a hole
oh okay yes i do see it
where is the hole? what are the coordinates?
4,3
(4,3) is not the correct location it should be (-4,3) since you go over to the left in the negative x direction
my negative didnt go in sorry
y = 3 is the y coordinate of the hole so y = 3 is NOT a possible output, which means it is NOT in the range of the function
so the range is the set of all real numbers BUT y can't equal 3
okay
if your teacher went over set notation, then you would write it like this \[\Large \left\{y|y\in\mathbb{R} \ , \ y \neq 3\right\}\]
thank you
or you can do it in interval notation \[\Large (-\infty, 3) \cup (3, \infty)\]
