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) = 2x3 - 2x2 - 3x - 5; lower bound?

Answer with explanation:

The given expression is

By rational root theorem, the possible factors of f(x) is,

→So, root of the above equation can't exceed .

So, K=4, can only be upper bound.

→k=4-----[Upper Bound]

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !
