Complete the following table using the equation: y = -2x²
1 answer:
The parabola is a downward parabola which is passing through origin and leading coefficient of the negative 2.
<h3>What is the parabola?</h3>It's the locus of a moving point that keeps the same distance between a stationary point and a specified line. The focus is a non-movable point, while the directrix is a non-movable line.
The equation of a quadratic function, of vertex (h, k), is given by:
y = a(x – h)² + k
where a is the leading coefficient.
The equation of the parabola will be
y = -x²
The given parabola is a downward parabola which is passing through origin and leading coefficient of the negative 2.
The graph of the function is given below.

Answer and Step-by-step explanation:
We are given the word format of an equation.
Let's right it out in numerical form.
The first part says One fourth the sum of x and 10
The sum of x and 10 would be shown as x + 10, and one fourth of that means that is multiplying (x + 10).
In this case, identical would mean equal to.
So, (x + 10) would be = to something.
It says that it is identical to x minus 4 (x - 4).
