Which equation is y = –6x2 3x 2 rewritten in vertex form? y = negative 6 (x minus 1) squared 8 y = negative 6 (x one-fourth) squ
AVprozaik [17]

The vertex form of the given equation, y = -6x² + 3x + 2, is expressed as: y = -6(x - 0.25)² + 2.375.

<h3>What is an Equation in Vertex Form?</h3>

The vertex form of an equation is expressed as, y = a(x - h)² + k, where:

(h, k) = vertex of the parabola.

Given the equation, y = -6x² + 3x + 2, factor the equation:

y = -6(x² - 0.5x) + 2

y = -6(x² - 0.5 + 0.0625) + 2.375

Rewriting the equation as perfect squares, we would have:

y = -6(x - 0.25)² + 2.375

The vertex form of y = -6x² + 3x + 2 is, y = -6(x - 0.25)² + 2.375.

Can someone pls help me
zavuch27 [327]
So the first thing you have to do is look at the input and output values and find the pattern. This is probably the hardest part. So 32-12=20 and 14-12=2 so we found the pattern all you have to do is find whats missing. So we have a blank and then a 14, all you do is add 12 to the 14 to find the input so the input for that would be 26 and now to find the other missing term you subtract 12 and that gives you -22. I hoped that helped.
