The graph represents the amount of snow, S, in inches as a function of time, t, in hours on a snow day.

Match each statement with the correct function notation.

• The amount of snow at 7 hours is less than the amount of snow at 1 hour.

• The amount of snow at 2 hours is greater than the amount of snow at 5 hours.

• The amount of snow at 6 hours is 3 inches.

• The amount of snow at 6 hours is equal to the amount of snow at 4 hours.

• The amount of snow at 7 hours is 0 inches.
