The function f(x) = -0,3x? * 2.5x + 5 can be used to approximate the distance a thrown ball is from the ground, where x is
the distance between the ball and the person throwing the ball. The mathematical domain of the function is all real numbers.
The reasonable domain of the function is when 0 sx sx but less than or equal to what value?
