Answer:
h = 10 + 8y
Step-by-step explanation:
Given that :
Height of ght if all alien at birth = 10cm
Growth rate per year = 8 cm
Let:
y = number of years since birth
h = alien's height in centimeter
Relationship between h and y
h = Initial height + (growth rate per year*number of years)
h = 10 + 8y
Answer:
x² - 2
Step-by-step explanation:
To obtain (g ○ f)(x), substitute x = f(x) into g(x), that is
g(x² - 3)
= x² - 3 + 1
= x² - 2
Answer:
y= 3+x
