Which if the following quartic functions has x = 1 and x =

Answers

Answer 1

Answer:

y = x⁴ +4x³ +4x² +4x +3

Step-by-step explanation:

The coefficients of the offered quartics (in order) have 1, 1, 1, and 0 sign changes, respectively. Descartes' rule of signs tells you this means the first three choices all have one (1) positive real root, so the negative real roots -1 and -3 are not the only ones.

The only possible polynomial is the last one. Synthetic division of that polynomial by roots -1 and -3 leave the remaining factor as x²+1, which has only complex zeros.

The appropriate choice is ...

... y = x⁴ +4x³ +4x² +4x +3

Yan is climbing down a ladder. Each time he descends 4 rungs on the ladder, he stops to see how much farther he has to go. If Yan made 8 stops with no extra steps, which expression best shows another way to write the product of the number of ladder rungs that Yan climbed? A: 4+4+4+4
B: 8+8+8+8
C: (-1)(4+4+4+4)
D: (-8)+(-8)+(-8)+(-8)

Answers

The correct answer is B. 8 + 8 + 8 + 8, OR 4*8
Each time he descends 4 rungs on the ladder, he stops to see how much farther he has to go, AND HE STOPS 8 TIMES, SO correct answer is 8*4 = 32
