Three roots of a fifth degree polynomial function f(x) are –2, 2, and 4 + i. which statement describes the number and nature of all roots for this function? f(x) has two real roots and one imaginary root. f(x) has three real roots. f(x) has five real roots. f(x) has three real roots and two imaginary roots.

Because the polynomial is of the fifth degree, we expect five roots.  If 4 + i is one of those roots, there must be a corresponding 4 - i.  We can conclude that there are two complex roots and three real roots.   The answer choice that involves the word "imaginary" cannot be correct; rather, we must use the word "complex" root to describe roots that have both real and imaginary parts.  "f(x) has three real roots" is the correct answer here.

step-by-step explanation:

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
