Given the data x 1 2 2. 5 3 4 5
f(x) 0 5 7 6. 5 2 0
(a) Calculate f (3.4) using Newton's interpolating polynomi­als of order 1 through 3. Choose the sequence of the points for your estimates to attain the best possible accuracy.
(b) Repeat (a) but use the Lagrange polynomial.

the correct answer is d

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
