How do I find my degree, leading term, leading coefficient, and end behavior of this polynomial: f(x)=3+2x^2-4x^3 Urgent!!!

Astandard deck of cards contains 52 cards. one card is selected from the deck. (a) compute the probability of randomly selecting a seven or king. (b) compute the probability of randomly selecting a seven or king or jack. (c) compute the probability of randomly selecting a queen or spade.

If f(x)=3x+1 and f^-1=x-1/3, then f^-1(7)=

True or false look at the picture pls : /
