Question

If the point (3,−5)
is on the graph of f(x)
, what point must be on the graph of f(−x)
?

Option #1: (3,5)


Option #2: (−3,−5)


Option #3: (−3,5)


(1 point)
The point in Option #
must be on the graph of f(−x)
.

Answer 1

Option #2.

Since f(3) = −5, for g(x) = f(−x) we have g(−3) = f(3) = −5. So the point (−3, −5) is on the graph of f(−x).
