Use synthetic division to determine whether the number k is an upper or lower bound (as specified) for the real zeros of the function f. k = 4; f(x) = 2x3 - 2x2 - 3x - 5; lower bound?

Answer with explanation:

The given expression is

By rational root theorem, the possible factors of f(x) is,

→So, root of the above equation can't exceed .

So, K=4, can only be upper bound.

→k=4-----[Upper Bound]

it's d.

step-by-step explanation:

because: -1(4x + 1y) +2 (1x-3y) distribute each number into the parenthesis.

then you would get: -4x - 1y + 2x -6y combine like terms

and get: 2x -7y

hope my answer has you if not then i'm sorry.

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
