Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
f(x) = 1 - x²
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em> [Function f(x)]: f(2x + 4) = 1 - (2x + 4)²
- Expand [FOIL]: f(2x + 4) = 1 - (4x² + 16x + 16)
- (Parenthesis) Distribute negative: f(2x + 4) = 1 - 4x² - 16x - 16
- Combine like terms: f(2x + 4) = -4x² -16x - 15

Answer:
(C) (2,0)
Step-by-step explanation:
The mid point of the line segment is defined as the point on that line that divides the line segment in to two congruent segments and is denoted as:
Mid point=
Now, the line segment having the points (-2,4) and (6,-4) has the mid point:
Mid point= 
=
Hence, the mid point of the given line segment is: (2,0)
Therefore, Option C is correct.
