Question

name
date:
lets name the functions that relate the weight of the star baby and the circle baby using function notation. each of the relationships relates to the babys weight and age.
the circle baby as a function of age: c(a)
the star baby as a function of age: s(a)

1. complete the chart below.

	circle baby	star baby
a. weight of the baby at 1 month	c(1) = ______	s(1) = ______
b. weight of the baby at 3 months	c(3) = ______	s(3) = ______
c. weight of the baby at 6 months	c(6) = ______	s(6) = ______

describe what each expression represents in this context:

a. c(5)	b. s(8)
s(0)	d. c(0)

uation c(2) = 11 can be interpreted as: \the circle baby, at two months, weighs 11
each equation mean in this situation?

= 11	b. c(9) = 15
15

Explanation:

Step1: Extract values from graph

From the scatter plot:

• $c(1)=7$, $s(1)=8$
• $c(3)=10$, $s(3)=11$
• $c(6)=13$, $s(6)=12$

Step2: Interpret function expressions

Match function input (age) to output (weight):

• $c(5)$: Circle baby's weight at 5 months
• $s(8)$: Star baby's weight at 8 months
• $s(0)$: Star baby's weight at 0 months (birth)
• $c(0)$: Circle baby's weight at 0 months (birth)

Step3: Interpret function equations

Translate equation to context:

• $c(9)=15$: Circle baby at 9 months weighs 15

(Note: The partial equation $=11$ and $=15$ are incomplete, only the full $c(9)=15$ is interpretable)

Answer:

Completed Chart:

	Circle Baby	Star Baby
b. weight of the baby at 3 months	$c(3)=10$	$s(3)=11$
c. weight of the baby at 6 months	$c(6)=13$	$s(6)=12$

Expression Meanings:

a. $c(5)$: The weight of the Circle baby at 5 months.
b. $s(8)$: The weight of the Star baby at 8 months.
c. $s(0)$: The weight of the Star baby at birth (0 months).
d. $c(0)$: The weight of the Circle baby at birth (0 months).

Equation Meaning:

b. $c(9)=15$: "The Circle baby, at 9 months, weighs 15."
(Note: The other partial equations are missing function names and cannot be fully interpreted with the given information.)
