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. Livia may eat only part of a cheese stick, so x may not always be a whole number.

A 2-column table with 4 rows. The first column is labeled x with entries 0, 2, 5, 7. The second column is labeled y with entries 11, 25, 46, 60.
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

y = 11 + 7x with x ≥ 0 (she can eat fractional sticks), so y can be any real number ≥ 11.
Answer: all real numbers greater than or equal to 11.
