Which polynomial lists the powers in descending order ?

Option B

Step-by-step explanation:

Polynomial having powers in descending order means x⁵ the x⁴ then x³ then x² then x.

Now we find polynomial which has the powers in descending order.

Option B.  4x⁵ - 3x⁴ - x³ - 2x² +1 is the only option arranged in descending order of powers.

picture below

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
