**What is the value of c in math?**

The c-value is where the graph intersects the y-axis. In this graph, the c-value is -1, and its vertex is the highest point on the graph known as a maximum. The c-value is where the graph intersects the y-axis. In this graph, the c-value is -1, and its vertex is the lowest point on the graph known as a minimum.
