Assume that an ArrayList of integers named a has been declared and initialized. Write a single statement that assigns a new value to the first element of the ArrayList. The new value should be equal to twice the value stored in the last element of the ArrayList.

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
