Question

Given the quadratic equation f(x) = 2x® -1, identify the following: 1. What is the minimum point on the graph of the function? A. (-1,0) C. (-1, 1) B. (0, -1) D. (1,-1)

Answer 1

The minimum of a quadratic function coincides with its vertex.

Given the general quadratic function :

$y=ax^2+bx+c^{}$

The x-coordinate of the vertex is computed as follows:

$x_V=\frac{-b}{2a}$
