Question

The graph of a quadratic function j is shown on the coordinate grid. The coordinates of the intercepts and the vertex are integers.

What is the minimum value of j?

Answer 1

To find the minimum value of a quadratic function, we need to determine the coordinates of its vertex. From the graph, we can use the x-coordinate of the vertex to find the minimum value of j.

Step-by-step explanation:

The minimum value of a quadratic function occurs at its vertex. To find the vertex, we need to determine the x-coordinate by using the formula x = -b/2a, where a and b are the coefficients of the quadratic function. From the graph, we can see that the x-coordinate of the vertex is an integer. Once we have the x-coordinate, we can substitute it into the quadratic function to find the corresponding value of j. This will give us the minimum value of j.

Answer 2

-2 -9 so that means the minimum of j is 9


Good luck.
