Graph the quadratic function. Determine the vertex, find the equation of the axis of symmetry, find any x- and y-intercepts, and state the domain and range in interval notation.f(x) = x2 - 6x

Question

A. vertex: (3, -9)
axis of symmetry: x = 3
x-intercepts: 0 and 6; y-intercept: 0
domain: (-?, ?); range: [-9, ?)
 
B. vertex: (-3, 9)
axis of symmetry: x = -3
x-intercept: none; y-intercept: 18
domain: (-?, ?); range: [9, ?)
 
C. vertex: (-3, -9)
axis of symmetry: x = -3
x-intercepts: 0 and -6; y-intercept: 0
domain: (-?, ?); range: [-9, ?)
 
D. vertex: (3, 9)
axis of symmetry: x = 3
x-intercept: none; y-intercept: 18
domain: (-?, ?); range: [9, ?)
