Question

2. Find the value of x^3 +2x^2 -3 when x =3
Answer-42

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
Answer-c

13. Write a function rule for the table shox
x 2 3 4
F(x) 2 1 0
Answer-f(x) = 2x

Answer 1

2) 27 + 18 -3 = 42 agree

12) I would say positive, burning time = k * height

13)f(x) = 2 - (x-2) = 4-x

Answer 2

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 = (2-1) / (2-3) = 1/-1 = -1.
m = (1-0) / (3-4) = 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.
