In a chemical reaction, the ratio between the concentration of the product and the concentration of the reactant depends on a variable x (for example, the initial amount of substance).[br]The ratio is modeled by the function: [math]\text{R(x)=\frac{x+1}{x-1}}[/math],[math]x\in\left[2;10\right][/math]
What is the maximum domain of definition of the function f(x)=R(x)[br][br][br]
[math]R-\left\{1\right\}[/math]
Describe how the concentration ratio changes as x increases.[br]
If x increases the concentration decreases.
What value does the ratio seem to approach?
Construct the graph of the function h(x)=f(x) on the maximum domain of definition in the window above.
