25/4=6.25
With respect to the <em>parent</em> function y = cos x, we have these function according to the order of the graphs:
- cos x
- cos (1/2)x
- cos 4x
- cos 2x
- cos (1/4)x
<h3>How to find the functions corresponding to each graph based on the period of a function</h3>
Mathematically speaking, cosines are <em>periodic</em> functions and period (T) is the distance in the <em>horizontal</em> axis such that f(t + T) = f(t). The period of the <em>parent</em> <em>cosine</em> function is 2π. Period in <em>daughter</em> functions may vary by means of the following form:
y = cos Ax (1)
Where:
- x - Independent variable
- y - Dependent variable
- A - Period width
Please notice that <em>daughter</em> functions report periods <em>longer</em> than in the <em>parent</em> function for 0 < A < 1 and a <em>shorter</em> one for A > 1. In consequence, these functions appear in the following order:
- cos x
- cos (1/2)x
- cos 4x
- cos 2x
- cos (1/4)x

Answer:
The revenue function is given as
R(x) = 500x - 0.8x²
Step-by-step explanation:
Given the Price equation
P = 500 - 0.8x
and the Cost equation
C(x) = 4x + 6000
The revenue function is given as
R(x) = xP
But P = 500 - 0.8x
So
R(x) = x(500 - 0.8x)
= 500×x - 0.8x×x
= 500x - 0.8x²
R(x) = 500x - 0.8x²
