Answer:
Option A.
Step-by-step explanation:
Note: The given function should be instead of .
Consider the given function is
We need to find the function which represents a reflection of f(x) across the x-axis.
If a function f(x) is reflected across the x-axis, then the new function is
Using this rule, we get
Therefore, the correct option is A.
48 is the perimeter, all sides in a square are equal, you take 12 * 4 which gives you 48.
For the area, you take two sides, length and width, and you multiply them, 12 * 12, this gives you 144.
