Question

If the function f(x)=(x+1)2
is reflected horizontally, how does the reflection affect the point (−2,1)
?(1 point)

In the horizontal reflection, the point (−2,1)
becomes (1,2)
.

In the horizontal reflection, the point (−2,1)
becomes (2,−1)
.

In the horizontal reflection, the point (−2,1)
becomes (2,1)
.

In the horizontal reflection, the point (−2,1)
becomes (−2,−1)
.

Answer 1

A horizontal reflection maps (x, y) to (−x, y). So (−2, 1) becomes (2, 1).
