The left ventricular length (viewed from the front of the heart) of a human fetus that is

Question:

The left ventricular length (viewed from the front of the heart) of a human fetus that is at least 18 weeks old can be estimated by
∫(x) = -2.318 + 0.2356x - 0.002674x²,
where ∫(x) is the ventricular length (in centimeters) and x is the age (in weeks) of the fetus.
(a) Determine a meaningful domain for this function.
(b) Find ∫′(x).
(c) Find and interpret ∫′(25).
