Answer:
third option
Step-by-step explanation:
Given
x² + 4x - 4 = 0 ( add 4 to both sides )
x² + 4x = 4
Using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(2)x + 4 = 4 + 4, that is
(x + 2)² = 8 ( take the square root of both sides )
x + 2 = ±
= ± 2
( subtract 2 from both sides )
x = - 2 ± 2
Answer:
I would choose f(x)= 3|x-1|
Step-by-step explanation: These are the point on the graph.
(X,Y)
-1,6
0,3
1,0
2,3
3,6
The answer would be 30 over 4
60,40,35,45,39
Put in order from least to greatest
35, 39, 40, 45, 60
Range = Max - Min
Range = 60 - 35
Range = 25
Answer
D) 25
