Answer:
Domain: ( -∞ , ∞ )
Range: ( -∞ , 4 ]
Explanation:
Hi there!
The domain tells us the possible x-values of a function. Because there are arrows at the end of each side, it means the graph is travelling infinitely to both the left and the right side. This means the the domain is all real numbers, meaning that for any value of x, there is a real value for y.
( -∞ , ∞ )
The range tells us the possible y-values of a function. Both sides of the graph are travelling infinitely downwards, starting from 4.
( -∞ , 4 ]
I hope this helps!
