Choose all answers that apply:

(Choice A)

5-2x

(Choice B)

x^4-8x^2-16

(Choice C)

5x^3+4x^4-3x+1

(Choice D)

None of the above

Answer 1

Answer:

Choice D.

None of the above.

Step-by-step explanation:

Standard form of polynomial is written as variable power in a decreasing order as shown below.

$ax^{n}+ bx^{(n-1)} +cx^{(n-2)}+............+x^{0}$

Here the power of x is decreasing from n to 0

So,

5-2x can be written as

$-2x^{1} +5x^{0}$

x^4-8x^2-16 can be written as

$x^{4}+0x^{3}-8x^{2} +0x^{1}-16x^{0}$  

5x^3+4x^4-3x+1  can be written as

$4x^{4} +5x^{3}+0x^{2}+3x^{1} + 1x^{0}$

Note: $x^{0} =1$
