Question

the graph of ( y = f(x) ) represents the amount of water in thousands of gallons remaining in a swimming pool after ( x ) days.
(a) estimate the initial and final amounts of water contained in the pool
the initial amount of water contained in the pool was ( square ) thousands of gallons

Explanation:

Step1: Understand the initial amount concept

The initial amount is when \(x = 0\).
From the graph, when \(x = 0\), \(y=50\) (by observing the \(y -\)intercept).

Answer:

50
