Question

Which quadratic function is in vertex form?

▸
Of(x) = 3x² + 6x - (-5)
Of(x) = 3x² + 6x +5
O f(x)= 3(x²+2x) +5
Of(x) = 3(x - 2)² + 5

Answer 1

The quadratic function in vertex form is:

Of(x) = 3(x - 2)² + 5

The vertex form of a quadratic function is given by f(x) = a(x - h)² + k, where (h, k) represents the coordinates of the vertex of the parabola.

In this case, the function Of(x) has the form 3(x - 2)² + 5, which matches the vertex form. The vertex of the parabola is at the point (2, 5).
