Question

y substituting the known values from the ordered pairs into the equation, we can find the constants A, B, C, and D.

Substituting (1, 6) in the equation by letting x=1 and f(x)=6, after doing the math and simplifying, we obtain 6 = A.
Substituting (2,11) in the equation, 11 = A + (2 – 1)B; so 11 = A + B.
Substituting (4, 39) in the equation, 39 = A + (4 – 1)B + (4 -1)(4 – 2)C; so 39 = A + 3B + 6C .
Substituting (7, -54) in the equation, we get -54 = A+ (7 – 1)B + (7 – 1)(7 – 2)C + (7 -1)(7 -2)(7 -4)D; so -54 =A + 6B + 30C + 90D.
The value of A is _
The value of B is
The value of C i

Answer 1

i got a.6

Answer 2

we have consider ordered pair: (1, 6) (2, 11) (4, 39) (7, -54). Each ordered pairs represents an (x, y)
