Question

Which represents the reflection of f(x) = StartRoot x EndRoot over the x-axis?

A 2-column table has 4 rows. The first column is labeled x with entries negative 1, 0, 1, 4. The second column is labeled f (x) with entries undefined, 0, negative 1, negative 2.
A 2-column table has 4 rows. The first column is labeled x with entries negative 1, 0, 1, 4. The second column is labeled f (x) with entries 1, 0, undefined, undefined.
On a coordinate plane, an absolute value graph starts at (0, 0) and goes down and to the left through (negative 4, negative 2).

Answer 1

Reflecting f(x) = √x across the x-axis gives g(x) = −√x. Domain: x ≥ 0. Values: g(0)=0, g(1)=−1, g(4)=−2, and undefined for x<0.

That matches the first table (undefined, 0, −1, −2), so the first option is correct.
