Need answer The domain of the following relation: R: {(-4, 8), (8, 10), (5, 4), (1, 6), (5,-9)}

{8, 10, 4, 6, -9}

{-4, 1, 5, 8}

{-4, 8, 5, 1, 5}

No domain exists

What is the value of the expression 9+n/3-6 when n = 12? 1. 5. 7. 12.

[10 points, algebra 2-simplifying complex fractions]according to my answer key the restrictions are -1 and 4. but why not positive 1?

Asequence has its first term equal to 4, and each term of the sequence is obtained by adding 2 to the previous term. if f(n) represents the nth term of the sequence, which of the following recursive functions best defines this sequence? (1 point) f(1) = 2 and f(n) = f(n − 1) + 4; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2n; n > 1 f(1) = 2 and f(n) = f(n − 1) + 4n; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2; n > 1 i will award !
