Question

Quadratic equation y = -2(x + 4)^2 + 3 what is the vertex

Answer 1

Answer:

Vertex is (-4,3)

Step-by-step explanation:

rewrite the problem from y=-2(x+4)^2+3 to y=ax^2+bx+c

y=-2x^2-16x-29

the parabola points are: a=-2  b=-16  c=-29

then divide x= -b/2(a)

x= -(-16)/2(-2)

simplify: x=-4

go back and plug in x=-4 to get y

y=3

Answer is (-4,3)
