Question

for the quadratic function ( f(x) = x^2 + 2x + 1 ), answer parts (a) through (f)

(a) find the vertex and the axis of symmetry of the quadratic function, and determine whether the graph is concave up or concave down.
the vertex is (square)
(type an ordered pair, using integers or fractions.)
what is the equation of the axis of symmetry?
the axis of symmetry is (square)
(use integers or fractions for any numbers in the equation.)
is the graph concave up or concave down?
(\bigcirc) concave down
(\bigcirc) concave up

(b) find the y - intercept and the x - intercepts, if any. select the correct choice below and, if necessary, fill in the answer box to complete your choice
(\bigcirc) a. the x - intercept(s) is/are (square).
(type an integer or a simplified fraction. use a comma to separate answers as needed.)
(\bigcirc) b. there are no x - intercepts.
what is the y - intercept? select the correct choice below and, if necessary, fill in the answer box to complete your choice.

Explanation:

Answer:

(a) Vertex: $(-1, 0)$; Axis of symmetry: $x = -1$; Concave up
(b) x-intercept(s): A. $-1$; y-intercept: $1$
