Question

If f(x)
is an even function and the point (x,y)
is on the graph of f(x)
, what other point must be on the graph of f(x)
?(1 point)

(y,x)


(−x,−y)


(−x,y)


(x,−y)

Answer 1

(−x, y)

Reason: For an even function f(−x) = f(x). If f(x) = y, then f(−x) = y, so (−x, y) is also on the graph.
