Answer:
The answer in the attached figure
Step-by-step explanation:
we have
This is a linear equation
The slope is equal to
The y-intercept is equal to the point ----> value of the function f(x) when the value of x is equal to zero
The x-intercept is equal to the point ----> value of x when the value of the function is equal to zero
using a graphing tool
see the attached figure

Answer:
Step-by-step explanation:
The function that could model this periodic phenomenon will be of the form
The tide varies between 3ft and 9ft, which means its amplitude is
and its midline is
.
Furthermore, since at the tide is at its lowest ( 3 feet ), we know that the trigonometric function we must use is
.
The period of the full cycle is 14 hours, which means
giving us
With all of the values of the variables in place, the function modeling the situation now becomes
