Question

What is the vertex of the graph of y = x2 + 2x + 1? (0, 1) (−1, 0) (−2, 1) (1, 4)

Answer 1

(-1,0)

Explanation:

the vertex is the highest or lowest point of a function where both lines meet and since (-1,0) is the lowest point and the next 2 are above it, so that makes (-1,0) the vertex.

Hope it helps the explanation is a little poor but I tried my hardest.

I attached a photo and if you look you can kind of see what I'm saying.
