Acertain element has a half-life of 69 years. an experiment starts with 1,500 grams of the element. the amount of the element remaining x years after the experiment began can be modeled with the function f(x) = 1,500(2)–x/69. the mathematical domain of the function is all real numbers. which statement describes how the reasonable domain compares to the mathematical domain? the reasonable domain is restricted to integers. the reasonable domain is restricted to positive real numbers. the reasonable domain has a minimum value of 1,500. the reasonable domain has a maximum value of 1,500

Have you ever been in the middle of telling a story and had to use hand gestures or even a drawing to make your point? in algebra, if we want to illustrate or visualize a key feature of a function, sometimes we have to write the function in a different form—such as a table, graph, or equation—to determine the specific key feature we’re looking for. think about interactions with others and situations you’ve come across in your own life. how have you had to adjust or change the way you represented something based on either the concept you were trying to describe or the person you were interacting with? explain how the complexity or layout of the concept required you to change your style or presentation, or how the person’s unique learning style affected the way you presented the information.
