Based on the information, it appears to be an exponentially growing infinite series, meaning that the answer is infinitely large. If you expand out the pieces, you can ignore all lower powers of x for purposes of inifinite series approximation. The total value, however, will be x^inf or x to the infinitieth power. So no limit is reached on this one...

1] at X = 0 the X terms = 0 so f(0) = d = -2 2] f(1) = 5 = a+b+c+d so a+b+c = 7 3] f(-1) = 3 = -a+b-c+d ==> take out d ==> -a+b-c = 5 4] add "a+b+c = 7" and "-a+b-c = 5" to get 2b = 12 b=6 5] f(2) = 4 = 8a +4b + 2c +d plug in b = 6 and d = -2 4 = 8a + 24 + 2c -2 8a + 2c = -18 ===> 4a + c = -9 6] Subtract "-a+b-c = 5" from "a+b+c = 7" to get 2a + 2c = 2 a + c = 1 ==> c= 1 - a 7] substitute 6] into 5] get 4a + (1-a) = -9 simplify to 3a = -10 a = -10/3 8] c = 1-a = 1 - (- 10/3) = 1 + 10/3 = 13/3 = 4 1/3 The key test is that you had 4 unknowns [a, b, c, d] and four equations. With more unknowns or fewer equations you could not solve this.

put x= 0 f(x) = d = -2 put x = 1 f(x) = a + b+ c - 2 = 5 or a + b+ c = 7 put x= -1 f(-1) = -a + b-c - 2 = 3 or -a + b -c = 5 add the 2 above equation to get b = 6 and a + c = - 1 so f(x) =a x^3 + 5 x^2 +c x - 2 put x = 2 f(2) = 8a + 20 +2c -2 = 4 8a +2c = -14 2a + 2c = - 2 subtact to get 6a = - 16 a = -16/6 b =

Zero (0). As the series contains a term (x-x) which results in 0 the product becomes 0.

I think it isn't 0 because those two x's [in (x-x)] has different meanings. Think f(x) = (x-a)(x-b)(x-c)...(x-z) then first x means the x-axis value and the second x means a constant. So If you replace the second x with x_0 then f(x) is not 0 always. It's a polynomial with 27 terms and the highest power of x is 26.

zero
as it has x-x which is 0
0 X anything is zero
this is an old grade 4 joke

It will be zero for obvious reasons. Give a sensible question next time.

0 (zero)
the equation contains (x-x) which will result the entire expression in 0.

answer is zero because this expresion will contain
a term (x-x) which is equal to zero i have already answered it before
