Let y=f(x) be the particular solution to the differential equation dydx=2x−1y2 with the initial condition y(0)=3. Which of the following is an expression for f(x) ?

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
