3. That looks like the same question as two I can't quite see it.
To find the vertex use -b/2a (for the x value which is also the axis of symmetry)
So 2/-2 = -1 Therefore the axis of symmetry is x=-1 Plug in for the y value:
y= -(-1)^2 -2(-1) + 1 y=-1 + 2 + 1 y=2 Vertex (-1,2)
The answer is 125
To solve:
(3+2)=5. *Parentheses first*
5^3 = 125
Answer:28
