To find the intercepts of a function, set one variable to zero and solve for the other variable. More information is needed to find the concentration of sugar when it is 1/15. More information or an equation is needed to solve for n.
To find the intercepts of a function, we set one of the variables to zero and solve for the other variable. This will give us the x-intercept (where the function crosses the x-axis) and the y-intercept (where the function crosses the y-axis). To find when the concentration of sugar in a tank is 1/15, we need more information about the function or the equation relating concentration of sugar to other variables. To solve for n, we need an equation or more context about the problem.
