Question

Really quick!!! Please help!!! Will fan and medal!

Use synthetic division to determine whether the number k is an upper or lower bound (as specified for the real zeros of the function f).

k = 4; f(x) = 4x4 - 3x3 - 2x2 - 5x - 4; Upper bound?

Answer 1

@zepdrix I thinks its upper bound

Specifically see the bottom part

"if all numbers on the bottom are positive or zero, then it is a upper bound of zeros on f(x)."

"if all number on the bottom are alternating in sign, then it is a lower bound of zeros on f(x)"

Answer 5

so woulf you say that its upper bound?

Answer 7

I don't know, you'll have to do the synthetic division to find out.

Answer 8

oh okay thank you!!
