Understanding Plant Growth Functions

The video tutorial presents a word problem involving a plant's growth and lifespan. It explains the concepts of domain and number types, focusing on integers and real numbers. The tutorial guides viewers in choosing the appropriate domain and determining the interval for the problem, emphasizing the importance of understanding the context rather than just the math.

What event marks the beginning of the plant's life in the word problem?

• The day it was bought

• The day it sprouted

• The day it was planted

• The day it was watered

Which type of number includes both whole numbers and decimals?

• Integers

• Real numbers

• Natural numbers

• Prime numbers

What does the domain of a function represent?

• The input values

• The output values

• The range of the function

• The maximum value

In the context of the word problem, what does 't' represent?

• The height of the plant

• The days from the time it was bought

• The age of the student

• The number of leaves on the plant

Why are real numbers chosen as the appropriate domain for the plant's lifespan?

• Because the plant's height is measured in whole numbers

• Because the plant can die at any time during the day

• Because the plant can only die on whole days

• Because the plant's age is a whole number

What is the interval for the domain of the plant's lifespan?

• -2 to 100

• 2 to 100

• -2 to 98

• 0 to 98

How many days before the purchase did the plant start sprouting?

• 0 days

• 2 days

• 3 days

• 1 day

What is the significance of the number 98 in the word problem?

• The number of days the plant was alive after purchase

• The number of days before the plant was bought

• The height of the plant in centimeters

• The number of leaves on the plant

What does the function H(t) represent in the word problem?

• The height of the plant over time

• The number of days the plant was alive

• The age of the student

• The number of leaves on the plant

Why is it important to consider the plant's life before it was bought?

• To calculate the total lifespan of the plant

• To know when to water the plant

• To determine the exact age of the plant

• To understand the plant's growth pattern
