(c)

To determine

### To find: The conclusions from the graphs and effects on the value of c .

Expert Solution

All the graphs are the same graph but with different y intercepts.

### Explanation of Solution

Given information:

The given function is f(x)=x2+c .

Calculation:

From the graphs in part (a) and (b), we can observe that all the graphs are the same graph but with different y intercepts.

In case when c is less than 0 , then the graph of y=x2+c is the same as the graph of y=x2 shifted c units upwards.

In case when c is greater than 0 , then the graph of y=x2+c is the same as the graph of y=x2 shifted c units downwards.

Therefore, all the graphs are the same graph but with different y intercepts.
