What is the sum of the roots of the polynomial shown below?
f(x) = x^3 + 2x^2 - 11x-12

Sum of the roots of the polynomial

Solution:

The general form of cubic polynomial is ---- (1)

If we have any cubic polynomial having roots

Sum of roots = ---(2)

From question given that,

--- (3)

On comparing equation (1) and (3), we get a = 1, b = 2, c = -11 and d = -12

Hence the sum of roots using eqn 2 is given as,

=

= -2

Hence the sum of the roots of the polynomial

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )

can i see the following ?
