Davion Holder · Answer 1

domain: (negative infinity, infinity) range: (5, infinity)

Dylan Hester · Answer 2

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 (-∞,∞).
