    Domain : (-∞,∞) Range : (-∞,∞)

    Step-by-step explanation:

    Given:

    f (x) = 3x+5

    To find: Domain and Range of f (x)

    Domain is the set of values that x can take.

    Range is the set of values of y corresponding to the values of x in the domain.

    Here x can take any value and the domain is the set of real numbers i. e (-∞,∞).

    f (x) = 3x + 5

    The graph of f (x) is a straight line that extends from - ∞ to + ∞ and hence the range is (-∞,∞).
