The faucet was turned on for approximately 10.8 minutes.
This problem pertains to the division operation in mathematics. Given that 48.6 liters of water came out of the faucet and that 4.5 liters come out each minute, we can find the time the faucet was on by simply dividing the total volume by the volume per minute: 48.6 liters / 4.5 liters per minute which equals approximately 10.8 minutes. Therefore, the faucet was on for approximately 10.8 minutes.

There is only one intercept at the origin - coordinates (0, 0).
We have the function f(x)=x²
Let y = x² We have to find out the x-intercept and the y-intercept
an x-intercept is a point on the graph where y=0 ⇒ x²=0 ⇒ x=0 ⇒ O(0,0) - x-intercept
a y-intercept is a point on the graph where x=0 ⇒y=0 ⇒ O(0,0) - y-intercept
↓
The function has only one intercept : O(0,0) as it is shown in the graph below ↓
