Question

The graph of an equation has a minimum y value of 12. This minimum occurs at an x value of 3. What is true of the graph of the equation?

Answer 1

Looking at this graph, you can see that the minimum point of the graph is at y = -3. The second way to find the minimum value comes when you have the equation y = ax^2 + bx + c. If your equation is in the form y = ax^2 + bx + c, you can find the minimum by using the equation min = c - b^2/4a.
