Apolynomial function has a root of 0 with multiplicity 1, and a root of 2 with multiplicity 4. if the function has a negative leading coefficient, and is of odd degree, which of the following are true? a. the function is positive on (-infinity, 0) b. the function is negative on (0, 2) c. the function is negative on (2, infinity) d. the function is positive on (o, infinity)

A,B and C are true.

Step-by-step explanation:

let f(x) be the given polynomial with variable x such that

m,where a be any odd degree negative leading coefficient of f(x),x has root as 0 with multiplicity 1 and has root 2 with multiplicity 4.

Lets check all the options

A. The function is positive on (-∞, 0)

let x=-1∈(-∞, 0)

⇒> 0 as a is negative.

∴ function is positive on (-∞, 0) .i,e. A is true.

B. The function is negative on (0, 2).

Let x=1 ∈(0,2)

⇒< 0 as a is negative.

∴ the function is negative on (0, 2) .i,e. B is true.

C. The function is negative on (2, ∞)

let x=3∈(2,∞)

⇒< 0 as a is negative.

∴ the function is negative on (2,∞).

D.The function is positive on (0, ∞) which is not true from C.

step-by-step explanation:

2/5+1/2=9/10

6/1-9/10=5.1

a negative exponent is translated as follows:

so, we have
