To get the average rate of change (ARC) of f(x) over [x1, x2], we use the formula:
ARC = ( f(x2) - f(x2) ) / (x2 - x1)
From the graph
f(2) = 4
f(-2) = 4
Plugging in the values into the formula:
ARC = (4 - 4) / (2 - (-2) )
ARC = 0
The points connecting (-2,4) amd (2,4) is a horizontal line that is the rate of change is 0.
Answer:

Step-by-step explanation:
Given
Solid Shape = Cube
Edge = 2 feet
Increment = 5 feet per minute
Required
Determine volume as a function of minute
From the question, we have that the edge of the cube increases in a minute by 5 feet
<em>This implies that,the edge will increase by 5m feet in m minutes;</em>
Hence,

Volume of a cube is calculated as thus;

Substitute 2 + 5m for Edge

Represent Volume as a function of m

I think the equation is written as 3r + 2.5p, where r is the number of roses and p is the number of petunias. To find the total cost, substitute 777 to r and 888 to p. The total cost would then be:
Total Cost = 3r + 2.5p
Total Cost = 3(777) + 2.5(888)
Total Cost = 4551
The total cost would be $4,551.
Absolute value is the same as modulus, thus
|-4 -sqrt(2) i |
=sqrt((-4)^2+(-sqrt(2))^2|
=sqrt(16+2)
=sqrt(18) = 4.243 (approx.)
