STEP 1

What is this asking?
When does the paper airplane hit the ground?
Watch out!
Don't confuse the $\text{x}$-intercept with the $\text{y}$-intercept!

STEP 2

1. Understand the x-intercept
2. Relate to the problem

STEP 3

Alright, so, what is an $\text{x}$-intercept?
It's where the graph crosses the $\text{x}$-axis!
And what does the $\text{x}$-axis represent?
It represents time in this problem.

STEP 4

So, the $\text{x}$-intercept is the time when the height is zero.
Think about it: any point on the $\text{x}$-axis has a $\text{y}$-value (or height) of zero.

STEP 5

Now, what does a height of zero mean for our paper airplane?
It means the airplane is on the ground!
It's landed!

STEP 6

So, the $\text{x}$-intercept tells us the time it takes for the airplane to go from the top of the building all the way down to the ground.
In other words, how long the airplane is in the air.

The correct answer is (d).
The $\text{x}$-intercept represents the number of seconds the airplane is in the air.
