Question

What are the domain and range of the function f(x) = 3x + 5? domain: (negative infinity, infinity); range: (0, infinity) domain: (negative infinity, infinity); range: (5, infinity) domain:(0, infinity); range: (negative infinity, infinity) domain: (5, infinity); range: (negative infinity, infinity)

Answer 1

Answer:

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 (-∞,∞).

Answer 2
