Question

Which description compares the domains of Function A and Function B correctly? Function A: f(x)=?3x+2

Answer 1

The domain of function A is all real numbers. There is no function B listed.

Explanation:

The domain is the set of all x values. This is the set of all numbers which are inputs to the function. Since function A is a linear function y = 3x + 2, it has all real numbers as its domain. It has no restrictions.

There is no function B listed to compare.
