The function $f (x) = a x^{2} + b x + c$ models the trajectory of a projectile, where $x$ is the horizontal distance in meters and $f (x)$ is the height in meters. If the projectile is launched from a height of 15 meters and reaches a maximum height of 40 meters at a horizontal distance of 25 meters, what is the value of $f (0)$ ?
