Answer:
- 40
Step-by-step explanation:
The absolute value function always returns a positive value, that is
| - a | = | a | = a
Given
| 43 - 99 | - | 75 + 21 |
= | - 56 | - | 96 |
= 56 - 96
= - 40

The function f(x) = 5x² + 40x is a parabola. Then the vertex of the parabola will be at (–4, –80).
<h3>What is the parabola?</h3>
It is the locus of a point that moves so that it is always the same distance from a non-movable point and a given line. The non-movable point is called focus and the non-movable line is called the directrix.
The function f(x) = 5x² + 40x
Then add and subtract 80, then we have
f(x) = 5x² + 40x + 80 – 80
f(x) = 5(x² + 8x + 16) – 80
f(x) = 5(x + 4)² – 80
The vertex of the parabola will be at (–4, –80).
