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) = 2x^3 - 2x^2 - 3x - 5; Lower bound?

loser66 · Answer

So, you have to solve for the zeros of the function. What are they?

anonymous · Answer

I'm honestly not sure how to find them

loser66 · Answer

use demos graph to see where they cut x-axis

anonymous · Answer

(2.2,0)

anonymous · Answer

So would the answer be no since it's (2.2,0) and 4 would be a higher bound and not lower bound?

loser66 · Answer

we don't have 0. please check

anonymous · Answer

what do you mean? it cut the x-axis at 2.2

loser66 · Answer

but you can use it. now find f(0) =?

loser66 · Answer

replace 0 into f(x) , what do you get?
