Question

Graph the function. Identify the vertex and axis of symmetry.

f(x) = –x2 – x + 2

a. axis of symmetry: x = –0.5
vertex: (–0.5, 2.25)

b. axis of symmetry: x = 0.5
vertex: (0.5, 2.25)

c. axis of symmetry: x = –0.5
vertex: (–0.5, –2.25)

d. axis of symmetry: x = 0.5
vertex: (0.5, –2.25)

Answer 1

the axis of symmetry = -b/2a
from ur equation f(x) = –x2 – x + 2
here, a=-1 and b=-1

Answer 2

then to get the vertex, it can be (-b/2a, f(-b/2a))

Answer 3
