Which second degree polynomial function has a leading coefficient of –1 and root 4 with multiplicity 2? f(x) = –x2 – 8x – 16 f(x) = –x2 + 8x – 16 f(x) = –x2 – 8x + 16 f(x) = –x2 + 8x + 16

ANSWER

EXPLANATION

If a second degree polynomial function has a leading coefficient of –1 and root 4 with multiplicity 2, then is equation is

We expand to get:

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .

step-by-step explanation:

m∠a is 90°

m∠b is 40°
