Answer:
2x^2 -14x +7
Step-by-step explanation:
(4x^2 -5x + 1)-(2x^2 +9x-6)
4x^2 -5x + 1 -2x^2 -9x +6
we have:
2x^2 -14x +7
Answer:
-1 x 2 = -2
Step-by-step explanation:
f(-1)=-1 x 2+1 = -1
-1 x 2 = -2
-2 + 1 = -1
g(-1) = 3 x -1 +5 = 2
3 x -1 + -3
-3 + 5 = 2

For the series:
- 5 + ( - 1 ) + 3 + 7 + 11
common difference between the numbers is 4 and a 1 = -5
The series in sigma notation:
4
∑ ( 4 i - 5 )
i =0
2 straight lines that never cross each other
