Final answer:
The domain of the function A = 500e^(0.0425t) is all real numbers, which means any real number can be substituted for 't'.
Step-by-step explanation:
The domain of a function refers to the set of all possible input values (commonly represented by 'x' or another variable) for which the function is defined. For the function A = 500e^(0.0425t), where 'A' represents the value of the function and 't' is the variable, the domain is all real numbers. This is because the exponential function e^x is defined for every real number 'x', hence 't' can take any real value, making the domain all real numbers, often denoted as (-∞, ∞).
