Question

let $f(m)$ represent the amount of water remaining in a pool $m$ minutes after it started draining. use the tiles to create true statements. $f(20)$ would be used to find the number of gallons of water remaining in the pool after $square$ minutes. $f(x) = 450$ means there are $square$ gallons of water remaining in the pool after $square$ minutes.

Explanation:

Step1: Analyze \( f(20) \)

The function \( f(m) \) gives water remaining after \( m \) minutes. For \( f(20) \), \( m = 20 \), so it's after 20 minutes.

Step2: Analyze \( f(x)=450 \)

In \( f(x)=450 \), the output (450) is gallons remaining, and the input \( x \) is minutes. So 450 gallons remain after \( x \) minutes.

Answer:

For \( f(20) \): 20
For \( f(x) = 450 \): 450; \( x \)
