Question

Hello can you please help me posted picture of question

Answer 1

The answer is C. (-2,-7)

you just have to find the solution to Y.

Answer 2

Vertex of a parabola exists at:


`( (-b)/(2a),y( (-b)/(2a)))`

b = coefficient of x term = 8
a = coefficient of squared term = 2

So,


`(-b)/(2a)= (-8)/(4)=-2`

and


`y(-2)=2(-2)^(2)+8(-2)+1=-7`

Therefore, the vertex occurs at (-2, -7)

So, the correct answer is option C
