We have found that the area of the garden is f(x) = x(49 - x). The domain of this quadratic equation is all real numbers, but in the context of this real-world problem we are only interested in the values of x that result in a non-negative area, so the domain will be the x-values that make f(x) > 0 Therefore, the domain of f(x) is as follows.
