Answer:
a+b
Step-by-step explanation:
Explanation:
f(x) = (x-4)(x+2)
1) For x-intercept, y will be 0
<u />
<u>x-intercept</u>: (4, 0), (-2, 0)
2) For vertex: x = -b/2a where ax² + bx + c
<u>Quadratic function</u>:
<u>vertex</u>:
y: (x-4)(x+2) = (1-4)(1+2) = -9
ordered pair of vertex: (1, -9)
3) For y-intercept, x will be 0
<u>y-intercept</u>: (0, -8)
Answer:
it will be 14.10 because 2.35x 6 equals 14.10$
Step-by-step explanation:
Answer:
Step-by-step explanation:a=2b+4
The function that represents the Scooter Company's total profit is given by:
P(x) = -2x² + 250x - 2,000.
<h3>How to calculate the profit function?</h3>
The profit function is calculated by the <u>revenue function subtracted by the cost function</u>, hence:
P(x) = R(x) - C(x).
In this problem, we have that:
- The revenue function is: R(x) = 400x - 2x².
- The cost function is: X(x) = 150x + 2000.
Hence the profit function is:
P(x) = R(x) - C(x).
P(x) = 400x - 2x² - (150x + 2000).
P(x) = -2x² + 250x - 2,000.
