A marine rescue center starts the year with 44 sea turtles. The table shows how the sea turtle population changes
each month. At the end of April, the center returns of
the sea turtles at the center to the sea. How many sea
furtles are returned at the end of April? Show your work.

step-by-step explanation:

the orientation of the parabolas can easily be found by analysing the power of x and y and their signs. if x is squared , parabola opens up and also if its coefficient is negative it opens down. if y is squared , the parabola opens right and also if its coefficient is negative it opens left. however in order to do the above analysis our equation must be in standard form .

our parabola is

which is not standard form of any parabola . hence we square on both hand side and convert it into standard form.

hence we see that x is squared and its coefficient is non negative . there for it opens up.
