Question

2.
Which of the following describes the parabola with the equation y = x2 + 2x + 1?

A. The axis of symmetry is x = −1 and the vertex is (−1, 0).

B. The axis of symmetry is x = 0 and the vertex is (0, 1).

C. The axis of symmetry is x = 1 and the vertex is (1, 4).

D. The axis of symmetry is x = 1 and the vertex is (1, 2).

Answer 1

Answer:

The answer is A. The axis of symmetry is x= -1 and the vertex is (-1,0)

Step-by-step explanation:

Answer 2

Answer: x=1

A. The axis of symmetry is x = −1 and the vertex is (−1, 0).

Step-by-step explanation:  graph{x^2+2x+1 [-10, 10, -5, 5]}

Explanation:

This is a quadratic equation so it makes a Parabola on a graph.

Information:

x-intercept: (1,0)

y-intercept: (0,1)

vertex: (1,0)

line of symmetry: x=1

...............................................................................................................................................

The answer is option a via completing the square

y= x^2+2x+1

y= (x+1)^2+1

so it will have an aos of -1 and a vertex of (-1,0)
