Apply quadratic fromula to solve the following problems: a) y = x2 + 1
y = x + 1

b) y = 5x – 20
y = x2 – 5x + 5

c) y = -0.5.x2 – 2x + 1
y + 3 = -x

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 !
