Question

The graph of quadratic function g is shown on the grid. The coordinates of the x-intercepts, the y-intercept, and the vertex are integers.

What is the minimum value of g?

Answer 1

-1

Explanation:

This quadratic function shows this equation:

`g(x)=(x-3)^2-1`

But you shouldn't need to know that! By observation, the minimum value of g is -1, because that is the lowest y value at the vertex on the graph! Since this is a parabola, we know that the graph will not have another minimum anywhere else!
