Determine whether the given function is a polynomial function. if it's a polynomial function, state the degree. if not, state the reason why. k(x) = –3x6 – 0.7x + x3 a. yes; degree 10 b. no, because some range elements correspond to more than one domain element c. no, because 0.7 isn't an integer d. yes; degree 6

ANSWER

The correct answer is option D.

EXPLANATION

The given function is

This a polynomial function. All degrees are greater than or equal to zero.

The coefficient being decimals does not disqualify it from being a polynomial.

The highest degree of this polynomial is 6.

Therefore the correct answer is D

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
