<span>Minimum wykresu funkcji kwadratowej znajduje się w ( -1, 2). Punkt ( 2 , 20) jest również od paraboli. Która funkcja reprezentuje sytuację?
</span><span>Canonical form of the function
</span>f(x) = a* (x - p)² + q
A .f(x) = (x + 1)² + 2 ⇔ p= -1 , q = 2
B. f(x) = (x – 1)² + 2 we reject
C. f(x) = 2(x + 1)² + 2 ⇔ p = -1 , q = 2
D .f(x) = 2(x – 1)² + 2 we reject
The point (2,20) substitute
A f(x) = (x +1)² + 2
20 = (2 + 1 )² + 2
20 ≠ 9 +2
20 ≠ 11 we reject
D f(x) = 2* (x + 1)² + 2
20 = 2* (2+1)² + 2
20 = 2 * 3² + 2
20 = 2 * 9 + 2
20 = 18 + 2

Answer:
The resort wants 1,536 visitors each week.
Step-by-step explanation:
512 x 3 = 1536
Times three is like tripling.
We need to check the ordered pairs for x = -2, x=5, x= 2/3 and x = 0.75.
1. For the first function: y = 9-4x
x=-2
The ordered pair is (-2,17).
x = 5
The ordered pair is (5,-11).
x = 2/3
The ordered pair is (2/3, 19/3)
x = 0.75
Answer:
16 (units)
Step-by-step explanation:
3.2<em>n</em>
<em>n</em> is a variable, so when you <em>let n = 5, </em>you substitute.
3.2<em>n</em> = 3.2 * 5 = 16 (units)
