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.
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, ∞)
