Maria’s bank automatically deactivates her debit card anytime she owes more than $50. Consider an equation where x is the balance of Maria’s account. What is the domain of this function that would keep her account activated? Write your answer in interval notation.

Answer 1

The domain of the function that represents whether Maria's account is activated can be represented as:
{ x | x > -50 }
This means that Maria's account will be activated as long as the balance is greater than -$50.

In interval notation, the domain can be written as:
(-50, ∞)
