Linear or Exponential Word Problems

Decide whether the word problem represents a linear or exponential function. . “A library has 8000 books, and is adding 500 more books each year.”

• Linear

• Exponential

Write an equation to represent the below situation “A library has 8000 books, and is adding 500 more books each year.”

• y=8000-500x

• y=8000*50^x

• y=500x+8000

• y=8000(1.5)^x

“There are 20,000 owls in the wild. Every decade, the number of owls is halved.” Can this be modeled with a linear or exponential equation?

• Linear

• Exponential

“There are 20,000 owls in the wild. Every decade, the number of owls is halved.” Write an equation to model this situation
