Answer 2

Answer:

• D) all non-negative integers

Step-by-step explanation:

The function f(x) = 10x + 50 models the total amount he has saved after 'x' months.

The domain is x-values, which is the number of the months.

x can only be zero or positive integers (since you can save after the month is complete), therefore the last option is correct.
