2. Find the value of x^3 +2x^2 3 when x =3
Answer42
12. What type of correlation would you expect between the number of minutes a candle burns and the height of the candle?
a. no correlation
b. positive correlation
c. negative correlation
d. equal correlation
Answerc
13. Write a function rule for the table shox
x 2 3 4
F(x) 2 1 0
Answerf(x) = 2x

2) 27 + 18 3 = 42 agree
12) I would say positive, burning time = k * height
13)f(x) = 2  (x2) = 4x 
2. 42 is correct!
12. c is correct.
13. X = 2,3,4.
F(x) = Y = 2,1,0.
(x,y)
(2,2)
(3,1)
(4,0).
m = (21) / (23) = 1/1 = 1.
m = (10) / (34) = 1/1 = 1.
m is the same @ all given points. So
the function is a linear Eq.
(2,2).
Y = mx + b = 2,
1*2 + b = 2,
2 + b = 2,
b = 4.
F(x) = x + 4.
