The function g(t) graphed below gives the ocean water surface elevation above NAVD 1988 in inches for 6 days in Nov. of 2017 at the Chincoteague Bay inlet in Chincoteague VA. t=0 represents Nov. 1, 2017. (NAVD 1988 is a vertical control of the primary height benchmark for the water in this inlet) Values above O represent an increase in water surface elevation above the NAVD 1988 vertical control and values below 0 represent a decrease in water surface elevation below the NAVD 1988 vertical control.

Question
The function g(t) graphed below gives the ocean water surface elevation above NAVD 1988 in inches for 6
days in Nov. of 2017 at the Chincoteague Bay inlet in Chincoteague VA. t=0 represents Nov. 1, 2017.
(NAVD 1988 is a vertical control of the primary height benchmark for the water in this inlet)
Values above 0 represent an increase in water surface elevation above the NAVD 1988 vertical control and
values below O represent a decrease in water surface elevation below the NAVD 1988 vertical control.
