find an equation in standard form of the parabola passing through the points (0, - 1), (1, 5), (- 1, - 5)

The equation of the parabola in standard is

Step-by-step explanation:

The standard form equation of the parabola is:

Using the three points we can find a, b and c.

Let's put the first point (0,-1)into the standard form equation.

Using the second point (1,5) and the value of c found above.

(1)

Finally using the las point (-1,-5)  

(2)  

Solving the system of equations (1) and (2) we can find a and b.

Adding both of them we have:

And b = 5.

Therefore, the equation of the parabola in standard form will be.
