Answer:
10. (-infinity, 6) Set Builder Form = { x : x < 6}
11. (4, infinity) Set Builder Form = { x : x > 4}
12. [-3,5) Set Builder Form = { x : -3 ≤ x < 5}
13. [-4,1]U[9, infinity) Set Builder Form = {x : x ∈ [-4,∞) - (1,9)}
14. (-infinity, infinity) Set Builder Form = {x : x ∈ (-∞,∞)}
Step-by-step explanation:
Set Builder form of a set states the general definition of the given function without specifying each and every element of set.
Now, here the given sets are:
10. (-infinity, 6)
Set Builder Form = { x : x < 6}
11. (4, infinity)
Set Builder Form = { x : x > 4}
12. [-3,5)
Set Builder Form = { x : -3 ≤ x < 5}
13. [-4,1]U[9, infinity)
Set Builder Form = {x : x ∈ [-4,∞) - (1,9)}
14. (-infinity, infinity)
Set Builder Form = {x : x ∈ (-∞,∞)}
