For the graph of the function, identify the axis of symmetry, vertex and the formula for the function.
A. Axis of symmetry: x = –1; Vertex: (–1, 0); f(x) = –x2 – 2x – 1
B. Axis of symmetry: x = –1; Vertex: (–1, 0); f(x) = –2x2 – 2x – 1
C. Axis of symmetry: x = –1; Vertex: (–1, –1); f(x) = –x2 – 2x – 1
D. Axis of symmetry: x = –1; Vertex: (–1, 0); f(x) = –x2 – x + 2
Axis of symmetry: x = –1; Vertex: (–1, 0); f(x) = –2x2 – 2x – 1
Step-by-step explanation:
What are the vertex and axis of symmetry of the equation?
The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola. For a quadratic function in standard form, y=ax2+bx+c , the axis of symmetry is a vertical line x=−b2a .
