Solution
Step 1:
The general parabolic function is given as:
If a is positive, the parabola is upward.
If a is negative, the parabola is downward.
Step 2
The c-value is where the graph intersects the y-axis. In this graph, the c-value is -3. The graph of a parabola that opens up looks like this. The c-value is where the graph intersects the y-axis.
Step 3:
Finally, the c-value can also be called the y-intercept of the parabola. Algebraically, this is where the x-value is zero and graphically, this is where the graph intersects the y-axis.
Final answer
The c value of the function represented in the graph is -3 because the parabola opens up.
