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.

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

to reflect a function over the x-axis, multiply the entire function by -1

so sqrt(x) reflected over the x-axis becomes -sqrt(x)

to figure out which table corresponds to this function, you could try plugging in the x-values (-1, 0, 1, and 4) into -sqrt(x) and see which one matches the y-values produced
