Web12 de out. de 2024 · How can you tell if a function is exponential by its graph? Graphs of Exponential Functions. The graph passes through the point (0,1) The domain is all real numbers. The range is y>0. The graph is increasing. The graph is asymptotic to the x-axis as x approaches negative infinity. The graph increases without bound as x approaches … WebAnswer: NO matter where you try to draw a vertical line, it only hits the graph once so this is a function. Be careful at x =2. The point (2, 1) is not filled in, indicating that the graph does not include the point (2, 1). However, notice that is completely filled in, because that point is included in the graph.
