Domain equation like # < x < #?
#TRIG

Because if so the first one should be something like
-inf < x < +inf
The arrows indicate that it keeps going and doesn’t stop at x = -4
The range would be
+inf < y < -inf
No domain refers to a set of all x values
And range is the set of y values

Because if so the first one should be something like
-inf < x < +inf
This is the domain for the first graph
The arrows represent continuous movement in some direction
(So infinite)
Closed circles: less OR greater represented by ≤ or ≥
Open circles: less, greater OR equal to, represented by: < or >
Arrows: in the court of domain and range, they represent continuous movement in a direction, so it’ll either be +∞ or -∞
But it’s asking for set and interval notation which I forgot what those are soo

I’m not sure how to write it in the form it’s asking
A)
domain: -∞ < x < +∞
range: +∞ < y < -∞
B)
domain: -4 < x < 3
range: -4 < y < 2
C)
domain: -2 < x <= 2
range: -3 < y <= -3
D)
domain: -∞ < x < +∞
range: -∞ < y < -∞
E)
domain: not sure
range: not sure honestly
I’m 100% sure for everything but E, but you’re supposed to put it in a certain form so you can just search up how to do that form
