How to complete the table?
Y_Kistochka [10]

Answer:

-2.75

-1.75

-0.75

0.25

1.25

Step-by-step explanation:

<em>The</em><em> </em><em>value</em><em> </em><em>of</em><em> </em><em>x</em><em> </em><em>is</em><em> </em><em>given</em><em> </em><em>in</em><em> </em><em>the</em><em> </em><em>top</em><em> </em><em>row</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>table</em><em>.</em><em> </em><em>We</em><em> </em><em>can</em><em> </em><em>complete</em><em> </em><em>the</em><em> </em><em>rest</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>table</em><em> </em><em>by</em><em> </em><em>plugging</em><em> </em><em>in</em><em> </em><em>the</em><em> </em><em>corresponding</em><em> </em><em>values</em><em> </em><em>of</em><em> </em><em>x</em><em> </em><em>into</em><em> </em><em>the</em><em> </em><em>equation</em><em> </em><em>and</em><em> </em><em>solve</em><em> </em><em>for</em><em> </em><em>y</em><em>.</em>

<em>F</em><em>or</em><em> </em><em>example</em><em>:</em>

y = (-2) - 3/4 = -2.75

y = (-1) - 3/4 = -1.75

y = (0) - 3/4 = -0.75

y = (1) - 3/4 = 0.25

y = (2) - 3/4 = 1.25

Can someone explain how to convert a quadratic function in standard form to vertex form using the "complete the square" method?
Arisa [49]

The required steps are explained below to convert the quadratic function into a perfect square.

<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.

Let the quadratic function be y = ax² + bx + c.

The first step is to take common the coefficient of x². We have

\rm y = a \left (x^2 + \dfrac{b}{a}x \right) + c

Add and subtract the half of the square the coefficient of x,

\rm y = a \left (x^2 + \dfrac{b}{a}x + \dfrac{b^2}{4a^2} \right) - a \times \dfrac{b^2}{4a^2} + c

Then we have

\rm y = a \left (x + \dfrac{b}{a} \right)^2 - \dfrac{b^2}{4a} + c

These are the required step to get the perfect square of the quadratic function.

More about the parabola link is given below.
