Answer:
option A
Step-by-step explanation:
Domain is the set of all x values and range the set of all y values where the function is defined.
In the first option we have graph on both sides of x. we have graph y for all x values . So, domain is (-∞, ∞)
There is no restriction for y. the graph is for all y values
So range is (-∞, ∞)
In the second option, the graph is above y axis so range is [0,∞)
In the third option, we have graph only for positive value of x
so domain is [0,, ∞)
In the fourth option , the graph is above y axis so range is [0,∞)
