but what about "to ensure Allied repayment of debts to the United States"?

Determine between which consecutive integers one or more real zeros of f(x)=3x^4+x^3-2x^2+4 are located? A. no real zeros B. 0 and 1 C. -2 and -3 D. -1 and 0 I was thinking it's either A or C? I need lots of help.

So then the answer would be (m + 4) (2a – 2) OR (m + 4) (a2 – 2)

Ok so the answer is (m + 4) (2a – 2) OR (m + 4) (a2 – 2)

Those aren't any of my choices Here is what i got 2^2 . 7^8 2^5 . 7^5 1/2^5 . 7^5 1/2^2 . 7 ^8

I saw the answer, but my choices are as follows: Thank you for your help but which one would it be? the thrid one or forth? I know the 1st two are no goes. You opinion please? Thanks! (m + 4) (a – 8) (m + 4) (a + 8) (m + 4) (2a – 2) (m + 4) (a2 – 2)

Thanks! That is what I thought, but why is this the answer? How does the probelm work it self out to be like that?

So how do we arrive @ this answer?

I do not need to mutiply anything. I just need to simplify this. (2^-1∙7^-4)^-2 So the final answer is 2^2 x 7^8 ? but how did we get this?

Thanks that is what I thought because you take the numbers and subtract them without the absolute value signs. Thanks!

(a) Find the y-intercept for the given line. (b)Find the slope for a line parallel to the given line. (c) Find the slope for a line perpendicular to the given line.

What is another name for food for bacteria? It's a suffix for multi-

What was the answer? Thanks

A. f is an odd function B. f is an even function C. f is neither odd nor even D.f is both odd and even Totally confused and would appreciate some insight. Thanks!

So I would say that the answer would be that f can be both odd and even then. Am I correct?

Yes I read them, but misinterpreted them I suppose. So this is an even function because x is being represented rather than y and this would be an even function resulting in a reflection in the y-axis? I will sketch it out.

If this was a -f(x) then it would be odd? I think I understand now..Am I correct?

I do not think these answers are right. I get somethin else and 5 is not an option. Here are the choices A. Minimum is 25 B. Minimum is -51 C. Maximum is -1 D. Maximum us -51

I was thinking that as well! Thanks!
