If there is 520 grams of radioactive material with a half-life of 12 hours, how much of the radioactive material will be left after 72 hours and is the radioactive decay modeled by a linear function or an exponential function?

Determine the domain and range of the given function. the domain is all real numbers all real numbers greater than or equal to –2{x: x = –2, –1, 0, 1, 2}{y: y = –2, –1, 0, 1, 2}. the range is all real numbers all real numbers greater than or equal to –2{x: x = –2, –1, 0, 1, 2}{y: y = –2, –1, 0, 1, 2}.
