This question has several parts that must be completed sequentially. If you skip a part of the question, you will not receive any points for the skipped part, and you will not be able to come back to the skipped part.

Consider the following.

Exercise (a) Find the coordinates of a second point on the graph of a function f if the given point is on the graph and the function is even. Exercise (b) Find the coordinates of a second point on the graph of a function f if the given point is on the graph and the function is odd.

g(t) = t − 43

The function is even.

The function is odd.

The function is neither even nor odd.

f(x) = −|x − 2|

The function is even.

The function is odd.

The function is neither even nor odd.

Determine whether the function is even, odd, or neither algebraically, graphically by using a graphing utility to graph the function, and numerically by using the table feature of the graphing utility to compare f(x) and f(−x) for several values of x.

(a) algebraically f(−x) = f(x)

f(−x) = −f(x)
