    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 ∈ (-∞,∞) }
