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 (2,1)
.

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 (1,2)
.

Answer 1

Correct answer: In the horizontal reflection, the point (-2, 1) becomes (2, 1).

Reason: A horizontal reflection across the y-axis changes x to -x while leaving y the same, so (-2,1) → (2,1).
