Question
4. Researchers at Iowa State University and the University of Arkansas have developed a piecewise function that
can be used to estimate the body weight (in grams) of a male broiler during the first 56 days of life according to
W(t)=48+3.64t+0.6363²+0.00963 t³ if 1St≤28,
-1004+65.8t if 28<t≤56.
Where t is the age of the chicken (in days).
a) Determine the weight of a male broiler that is 25 days old.
b) Is W(t) a continuous function? Explain.
