Answer:

Below

Explanation:

Multiplying the equation by -1 will flip it around the x - axis

so 3(x-2)^3

The equation of this function after it is reflected over the x-axis is option D.
$f(x)=3(x+2)^3$.

The image shows a function
$f(x)=-3(x+2)^3$ and asks for the equation of the function after it is reflected over the
$x$-axis.

To reflect a function over the
$x$-axis, you multiply the output (y-value) of the function by -1 . If the original function is
$f(x)$, after reflection over the
$\mathrm{x}$-axis it will be
$-f(x)$.

Given the function
$f(x)=-3(x+2)^3$, we will apply this transformation:

The reflected function is
$-\left(-3(x+2)^3\right)=3(x+2)^3$.

So, the correct answer is:


$$f(x)=3(x+2)^3$$

Among the given options, the correct one is:

D.
$f(x)=3(x+2)^3$
