As infants grow from a toddler to a young adult, there may be times when they are ill and medication is needed. It is extremely important that medication be administered in the exact dose so the child receives the correct amount. Too little or too much medication could have serious side effects. A popular children’s fever medicine manufacturer recommends the following dosage information to parents and pediatricians.


Children’s Fever Medicine

Weight
24+ lbs
36+ lbs
48+ lbs
60+ lbs
72+ lbs
Dosage
5 mL
7.5 mL
10 mL
12.5 mL
15 mL

Answer:

Every weight range goes up 2.5mL

24+=5mL

+2.5 in the 36+=7.5mL

I am not sure the second answer

Step-by-step explanation:

Using function concepts, it is found that:

a) The rate of change is of 0.2083 ml/lb.

b) Since the rate of change is constant, the function is linear.

Item a:

  • The input is the weight.
  • The output is the dosage.
  • The rate of change is given by the change in the output divided by the change in the input.

From the table, when the weight changes by 12 lbs, the dosage changes by 2.5 mL, hence:

[tex]r = \frac{2.5}{12} = 0.2083[/tex]

The rate of change is of 0.2083 ml/lb.

Item b:

Linear functions have constant rate of change, hence, since the rate of change is constant(0.2083 ml/lb), the function is linear.
