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