Answer:
<h2>
y = x² - 1</h2>
Step-by-step explanation:
y = -1 for x = 0 {point(0, -1)} means -1 at the end of formula
If we add 1 to y-coordinate of every given point we get the squares of x-coordinate:
(1, 0): 1² - 1 = 0
(2, 3): 2² - 1 = 4 - 1 = 3
(3, 8): 3² - 1 = 9 - 1 = 8
(4, 15): 4² - 1 = 16 - 1 = 15
So for any x:
(x, y) y = x² - 1
Answer:
- the amount spent (in thousands) is the x-coordinate of the vertex
- the maximum profit (in thousands) is the y-coordinate of the vertex
Step-by-step explanation:
The function describes a downward-opening parabola. (It is 2nd-degree with a negative leading coefficient.) So, the vertex of the graph will answer both questions at once.
You can put the function into vertex form by factoring the leading coefficient (-2) from the x-terms, adding the square of half the x-coefficient inside parentheses (and subtracting the same quantity outside parentheses), then writing the result in the form ...
P(x) = -2(x -h)^2 + k
The vertex is (h, k), so the answer is "h" thousand dollars spent on advertising will result in a maximum monthly profit of "k" thousand dollars.
__
The first two steps look like ...
P(x) = -2(x^2 -6x) -4
P(x) = -2(x^2 -6x +9) -4 -(-2)(9)

It can also be useful to use a graphing calculator to make a graph of the function.
