The domain of the function \( f(x) = 2(5)^x \) is all real numbers, denoted as \( (-\infty, \infty) \). This is because you can input any real number for \( x \) without restriction, allowing for a full range of outputs. The range of the function is \( (0, \infty) \) since the exponential function will never output a negative value or zero. The factor of 2 only stretches the graph vertically but does not change the fact that the outputs will always be positive, starting from just above zero and going upward infinitely.
