Question

Mr. Richardson is using a pump to drain the community pool. This function describes the depth of the pool, in feet, after x hours.
y=
–
0.6x+4
What does the number 4 represent?

Answer 1

In the equation \( y = -0.6x + 4 \), where \( y \) represents the depth of the pool in feet after \( x \) hours, the number 4 represents the initial depth of the pool when \( x = 0 \). In other words, when no time has passed (or at the start of the draining process), the depth of the pool is 4 feet.
