Answer:
Step-by-step explanation:
Let's start by using distributive multiplication:
So:
Grouping like terms:
Now, 
is equal to:
In this sense:
In order to satisfied the equality:
Hence, from (1), let's solve for a:
And from (2), let's solve for b:
Let's verify the result evaluating the values of a and b into the original equation:
As you can see, the values satisfy the equation, therefore, we can conclude they are correct.
1 plant would cost you $1.96. cause in one tray has 16 plant you divide that into $8.15 and you'll get $1.96 for one plant.
Next time you should write the correct form of equation
because it affects greatly the answer. I believe the correct form would be:
f (x) = 2 * x^2 + 1
where the second 2 is a power of x
The average rate of change is also defined as the slope
of the equation. Therefore:
average rate of change = slope
Where slope is:
m = (y2 – y1) / (x2 – x1) = [f (0) – f (-1)] / (x2 – x1)
Calculating for f (0): x2 = 0
f (0) = 2 * 0^2 + 1 = 1
Calculating for f (-1): x1 = -1
f (-1) = 2 * (-1)^2 + 1 = 3
Substituting the known values to the slope equation:
average rate of change = (1 – 3) / (0 – 1)
average rate of change = -2 / -1
average rate of change = 2
