Answer:
4
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
Here [ a, b ] = [ 3, 4 ] , then
f(b) = f(4) = - 1 ← from table
f(a) = f(3) = - 5 ← from table , then
average rate of change = =
= 4

Answer:
The graph of given function is shown below.
Step-by-step explanation:
The given function is
.... (1)
We need to find the graph of the function.
The vertex form of the quadratic function is
.... (2)
On comparing (1) and (2) we get
It means the vertex of the function is (0,5).
The table of values is
x y
-2 1
-1 4
0 5
1 4
2 1
Plot all ordered pairs on a coordinate plane and connect them by a free hand curve.

Let's bear in mind that 5 gallons with a solution of 6% bleach, contains some water plus some bleach, how much bleach? well, is just 6% of 5 gallons or namely (6/100) * 5 gallons, or 0.30 gallons.
if we use "x" gallons of water, well pure water has no bleach, so is 0% bleach, and it has a (0/100) * x or 0x gallons of bleach.
the mixture will be say "y" gallons, and is 4% bleach, so (4/100) * y is 0.04y gallons in the mixture of bleach.
