Someone plz

#1. given f(x) and g(x) = k⋅f(x), use the graph to determine the value of k.

two lines labeled f of x and g of x. line f of x passes through points negative 4, 0 and negative 2, 2. line g of x passes through points negative 4, 0 and negative 2, negative 10.

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 !
