come on. can't tell even and odd numbers?!?!? x^5-x = x^5 - x^1 5 and 1 are both odd, so f(x) is odd 5 = 5x^0 0 is an even power, so f(x) is even x^4 + 2x^3 4 is even, 3 is odd, so f(x) is neither even nor odd.

Polynomials with all terms in even degree are even functions, and those with all odd degree terms are odd functions. For this purpose, a constant k can be considered as k*x^0, so it is even. A mix of even and odd degree terms is neithter odd nor even. Example: f(x)=x^6+x^2+4 ...

If the difference is odd, one of the numbers must be even, the other odd. So, the odd must end in 5. 12-5=7, so the even number ends in 2 we know the even number does not begin with 0, so its middle digit is 8. 10-4 = 6, but we borrowed. So, 802 - 645 = 157

If you multiply two odd numbers, would you expect the product to be odd or even?

Determine whether the function is even, odd, or neither. f(x)=-4x+5x Its odd right?

add the last numbers in each number such as your example, 3+5+4+7 and if that's odd then the total is odd same for even

Discrete Mathematics
any odd number can be written in the form 2n + 1 , where n is a positive integer. (2n+1)^2 = 4n^2 + 4n + 1 = 4(n^2 + 1) + 1 since any integer multiplied by 4 is even, the term 4(n^2 + 1) is even , adding 1 to it would make it odd.

algebra
if n is even, then (-1)^(n+1) = -1 if n is odd, then (-1)^(n+1) = +1 if n is not an integer, then (-1)^(n+1) is undefined So, if n is even, your expression is -2 if n is odd, your expression is +2

math
all prime numbers, except the number 2, are odd numbers. The sum of any two odd numbers is always even. So the sum of any 4 prime numbers, with the exception of that lonely 2, will always be even. e.g. 3+5+7+11 = 26 which is even.

assuming you mean even and odd, just check: 2 4 6 8 1 3 5 7 9 which kind occurs an odd number of times?

Auppose f is even but g is an arbitrary function (possibly neither even nor odd). (a) Is f o g still even? Show why or why not. (b) Is g o f even? Show why or why not.

No. There are many possible a,b,c combinations that obey the right angle rule a^2 + b^2 = c^2 and for which a, b, and c are all integers. However, if they all ODD integers, a^2, b^2 and c^2 would also be odd. That is impossible because two odd integers add (or subtract) to ...

Determine whether the function x^3+x^2-1 is even, odd or neither. I thought it was odd because it has one negative sign is this correct

How do you use possible symmetry to determine whether the graph is the graph of an even function, an odd function, of a function that is neither even or odd?

precalc
The question is: is (root(x2+2))/x=f(x) even or odd? I got that it was odd because f(-x)=-f(x) but on the graph it does not look like it is symmetric to the origin what did i do wrong?

make a conjecture for the following show work the sum of an even and odd number. - the product of two odd numbers.

Math
a) they are odd but 1/x is undefined at x = 0 b) linear but x is odd and |x| is even c) d/dx (2^x) = 2^x ln 2 so both derivatives keep repeating but sin x is periodic

I dont understand how you determine whether a function is even, odd,or neither. Here are my problems: Determine whether the given function is even, odd, or neither. 8. f(x)=x^3-x^2 This is how I did it. f(-x)=(-x^3)- (-x^2)= (-x)(-x)(-x) - (-x)(-x) = (-x^3) -(x^2)- I got that ...
