Question

If the point (13,−7)
is on the graph of f(x)
, what point must be on the graph of f(−x)
?(1 point)

The point (13,7)
must be on the graph of f(−x)
.

The point (−13,−7)
must be on the graph of f(−x)
.

The point (−13,7)
must be on the graph of f(−x)
.

The point (13,−7)
must be on the graph of f(−x)
.

Answer 1

Answer: (−13, −7).

Reason: If f(13) = −7, then for g(x) = f(−x) we have g(−13) = f(−(−13)) = f(13) = −7, so the point (−13, −7) is on g.
