Best ResponseYou've already chosen the best response.1This question is phrased a little strangely which makes it hard to understand exactly what they want. But consider this, 1. We know that (5,4) is on the graph of f(x). That is, "When x = 5, then y = 4." 2. This means that f(5) = 4. In English, "When x = 5, then y = 4." (same thing) 3. We are to find the "corresponding point" for f(1/3x). This sounds weird. 4. But, all we know is that f(5) = 4. This is the only information we have. 5. But look! I can be clever and do this... 6. Take f(1/3 x) and plug in x = 15. Then, 7. f(1/3 * 15) = f(5) = 4. 8. So the corresponding point must be x = 15 and y = 4. That is, (15, 4).
