Which of the following are subspaces of p3? support your answer.
a. u = { f(x) | f(x) ∈ p3, f(2) = 1}
b. u = {xg(x) | g(x) ∈ p2}
c. u = {xg(x) | g(x) ∈ p3}
d. u = {xg(x) + (1−x)h(x) | g(x) and h(x) ∈ p2}
e. u = the set of all polynomials in p3 with constant term 0
f. u = { f(x) | f(x) ∈ p3, deg f(x) = 3}

300

step-by-step explanation:

28-600w < 300

28-600w > 300

600-28w < 300

600-28w > 300

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.

step-by-step explanation:

1/800 is the right answer

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3
