Which polynomial is in standard form?

B

Step-by-step explanation:

Standard form is just descending powers.

Highest power in the polynomial is 5,

Second highest is 2,

Third Highest is 1 (x^1 = 9x)

Lowest is x^0 (the 12 is actually 12*x^0 = 12*1)

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).

the answer is c)8
