Quadratic Functions: Vertex Form Answers

The graph of which function is decreasing over the interval (–4, ∞)?

The graph of f(x) = x2 is translated to formg(x) = (x – 2)2 – 3.Which graph represents g(x)?

On a coordinate plane, two parabolas open up. The solid-line parabola, labeled f of x, goes through (negative 2, 4), has a vertex at (0, 0), and goes through (2, 4). The dashed-line parabola, labeled g of x, goes through (negative 5, 8), has a vertex at (negative 3, 4), and goes through (negative 1, 8).

The graph shows the axis of symmetry for a quadratic function f(x).
