Question

Identify the vertex, axis of symmetry, minimum or maximum value, and range of each parabola.

1. y=x^2+2x+1

2. y=x^2+4x+1

3. y=3x^2-4x-2

4. y=2x^2-6x=3

Answer 1

i do for the first one
and you go over others
\[y=x^2+2x+1 =(x+1)^2 \]
so vertex is at x+1=0
so x-1
y=0 too
vertex is (-1,0)
