Expert Solution

Answer to Problem 70E

All the graphs are the same graph but with same y intercepts and different intercepts on x axis.

Explanation of Solution

Given information:

The given function is f(x)=(xc)2 .

Calculation:

From the graphs in part (a) and (b), we can observed that all the graphs are the same graph with same y intercepts and different intercepts on x axis.

In case when c is less than 0 , then the graph of y=(xc)2 is the same as the graph of y=x2 shifted c units to the left.

In case when c is greater than 0 , then the graph of y=(xc)2 is the same as the graph of y=x2 shifted c units to the right.

Therefore, all the graphs are the same graph but with same y intercepts and different intercepts on x axis.
