Answer:
f(x) = x(x-1)
Step-by-step explanation:
The easy way to do this is to look at it graphically. an inverse function is reflected across the line y=x. f(x)=x(x-1) is an upward opening parabola when reflected, there are two y-values for all positive values of x. A function can only have one y for every x.
Let the length be x and the width be y
the perimeter of the rectangle will be:
2x+2y=376
thus
y=188-x
thus the area will be:
A(x)=x(188-x)
A(x)=188x-x^2
For maximum Area A'(x)=0
from Area we shall have
A'(x)=188-2x=0
solving for x we get:
x=94
thus the width will be:
188-94=94
thus for maximum area the length=94 ft and width=94 ft
Area=94*94=8836 ft^2
thus the answer is:
<span>c. 94 x 94; 8836ft </span>
Answer:
If your trying to find m then
-10 = 2m + 4
-4 -4
-14 = 2m
then you divide
-14/2 and 2/2 < this one cancels out
-7 = m
Answer:
<em>Rate of Change = 4</em>
Step-by-step explanation:
The starting point (x=0) is (0, -2)
The ending point (x=2) is (2, 6)
The distance between the two points in rise over run terms is 8/2
