[bws.02] jim plans to plant coffee beans on the farm. coffee needs warm, moist, and sunny climate. it always snows for four months, starting from november, in the location where jim lives. the temperature is generally moderate from june to october. based on scientific knowledge, which of these would be the best month to plant coffee?

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
