The IDENTITY keyword is used to modify a column name, and is used to specify surrogate keys. The first number parameter after IDENTITY specifies the starting value for the surrogate key, and the second number specifies the increment value for each additional record. Thus a column named RelationID and modified by IDENTITY (4000, 5) will be a surrogate key named RelationID with an initial value of 4000 (for the first record in the relation), and with following values incremented by 5: 4000, 4005, 4010, etc.

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )

7x7=4 so if u carry the 9 it will be 33

this would be 35. 35 + 5 = 40. you take the known constant and subtract by the answer of the equation and you get y.
