Answer:
f(x):

g(x)

Step-by-step explanation:
When a function is of the form:

The equation of the axis of symmetry is

The given function is

We can see that h=-4
Hence the equation of axis of symmetry is

From the graph, the axis of symmetry of h(x) is the vertical line that divides the parabola into two congruent halves.
This line is

25 feet above sea level means she travelled 25 feet to the surface of the sea. She would have to descend (37-25=12) 12 more feet to achieve 37 total feet of travel, so she descended 12 feet below sea level.
