Give the formula of the quadratic function f in general form
The range of the quadratic function f is (−∞, 4], the axis of symmetry of its graph is the line x = −1, and f(0) = 1.
Which formula describes the quadratic function whose graph is shown in the figure?
y = f(x)
Give the formula of the function f in general form
The figure shows the graph of a quadratic function f. The point V is the vertex of the parabola and the point A lies on the parabola. Both points lie on grid nodes.
Give the formula of the quadratic function f in general form
The vertex of the parabola that is the graph of the quadratic function f is the point (3, −4), and the graph passes through the point (6, 14).
Which formula describes the quadratic function whose graph is shown in the figure?
y = f(x)
