Question

Jen has a peanut butter sandwich on white bread each day. The number of calories C in the sandwich, as a function of the number of grams P of peanut butter, is C= f(P) = 174 + 6P. (I need help with questions (e) and (f) for this problem).

Answer 1

The function is:

f(P)=174+6P

where P is the number of grams of peanut.

e. f(P)=234 represents

If P gram of peanut butter are on teh sandwich than the sandwich have 234 total calories.

f. f(P)=174+6P

Thus, P=[f(P)-174]/6.

The most reasonable domain and range for this function is

domain: (0,50)

range: (174,474)
