PLEASEEEE HELPPP!!!!!PLEASEEEEEEEEEEEEE!!!!!!!!Assessment practice!!!!it's URGENT HELP is much appreciated find the vertex of each equation. Then use a table to graph each quadratic equation

Answer 1

Remember that the x-coordinate of the vertex of a quadratic function is -b/2a. In this case is:

$x=-\frac{4}{2\cdot1}=-2$

the y coordinate is

$y=4+4\cdot-2-6=4-8-6=-10$
