Find the vertex, the line of symmetry, the maximum or minimum of the quadratic function, and graph the function.

f(x)=x^2-4x-3

What is the vertex? (Type an ordered pair)

What is the equation of the line of symmetry?
x=

What is the maximum/minimum of f(x)?

Is the value, f(2)= -7 a minimum or maximum?

  1. F(x) = X^2 -4X -3.

    V(h , k),
    h = Xv = -b/2a = 4/2 = 2,
    k = Yv = F(2) = 2^2 -4*2 -3 = -7,
    V(2 , -7).

    Line of sym.: X = h = 2.

    F(2) = -7 = min. (Eq opens upward)
