Question

which description compass the domains of function a and function be correctly rest of the information in the picture below please answer with the answer choices

Answer 1

Given:

Function A: f(x) = -3x + 2

And the graph of the function B

We will compare the domains of the functions

Function A is a linear function, the domain of the linear function is all real numbers

Function B: as shown in the figure the graph starts at x = 0 and the function is graphed for all positive real numbers So, Domain is x ≥ 0

So, the answer will be the last option

The domain of function A is the set of real numbers

The domain of function B: x ≥ 0
