Best ResponseYou've already chosen the best response.0Notice how the app shows you values for dy/dx and also Δy/Δx? It's asking you to set x to 0.75 and play with the Δx slider to find all the Δx's that bring Δy/Δx and dy/dx within 0.1 units of each other. When x = 0.75 the app shows us that dy/dx is 0.16. So basically it is asking you to find all Δx's where Δy/Δx is between 0.06 and 0.26. I've included an attached image where Δy/Δx is 0.06 (that is 0.1 exactly units away from dy/dx so that is within the 0.1 range). There are many more places where Δy/Δx is within 0.1 units. Think you can find the rest of them now? : )
