To graph y = 4, we make a horizontal line at 4 on the y axis. See image 1
Since it is a horizontal line on the y axis, no matter the input you have for x, the y value is going to be 4. So the points <span> (4, ) (5, ) = </span><span> (4, 4) (5,4 )
For your point ( , 2.59), this is saying y = 2.59 The missing value would be 0. our points are below assuming the information given is complete:
</span>(4, ) (5, ) ( ,2.59) = (4, 4) (5,4 ) (0,2.59)

Answer:
see the explanation
Step-by-step explanation:
we have the quadratic equation
This is a vertical parabola open downward
The vertex is a maximum
Find the x-intercepts of the quadratic equation
The x-intercepts are the values of x when the value of y is equal to zero
so
For y=0
Solve the quadratic equation
The formula to solve a quadratic equation of the form
is equal to
in this problem we have
so
substitute in the formula
therefore
This parabola has two x-intercepts representing the times when the dolphin's height above water is zero feet
