Question

Livia eats a chicken drumstick with 11 grams of protein. She also eats x cheese sticks, each with 7 grams of protein. The table shows y , the total number of grams of protein that Livia will consume if she eats x cheese sticks. What is the range of the function? all real numbers all real numbers greater than or equal to 0 all real numbers greater than or equal to 11 all integers greater than or equal to 11

Answer 1

A/C to question,
Livia eats a chicken drumsticks with 11gram of protein and she also eats x cheese sticks , each with 7 gram of protein.
if y represents total number of gram of protein that Livia will consume, then function can be written as,
y = 11 + 7x , where x is a real number greater than equal to zero. [as question mentioned x cheese sticks are eaten by Livia]
so, x ≥ 0,
or, 7x ≥ 0
or, 11 + 7x ≥ 11
y ≥ 11
hence, range of function is all real numbers greater than equal to 11.

Answer 2

The answer followed by the situation will be “all real numbers greater than or equal to 11” which says that she would always have more than the one she consumed.

The total drumstick she ate = 7x + 11 where x the total number of the stick that is either zero or more.
