Answer:
Step-by-step explanation:
A = 25% of 16 =
Selling price after reduction = 16 - 2 = $14
B= 25% of 14
= 3.5
Selling price = 14 - 3.5 = $10.5
C = 25% of 10.5
= 2.625 = $ 2.63
Selling price = 10.5 - 2.63 = $ 7.87

Step-by-step explanation:
<u>Quadratic Function</u>
Standard Form of Quadratic Function
The standard representation of a quadratic function is:
where a,b, and c are constants.
When the zeros of f (x1 and x2) are given, it can be written as:
f(x)=a(x-x1)(x-x2)
Where a is a constant called the leading coefficient.
We are given the two roots of f: x1=-3 and x2=4, thus:
f(x)=a(x+3)(x-4)
We also know that f(5)=8, thus:
f(5)=a(5+3)(5-4)=8
Operating:
a(8)(1)=8
Solving:
a=1
The function is:
f(x)=1(x+3)(x-4)
Operating:
Answer: x=-7
