are step functions even or odd?

Step 1: Replace f(x) with f(-x) and simplify the function. Step 2: Compare f(-x) to f(x) and -f(x). Step 3: Determine if the function is even, odd, or neither. Since f(-x) does not equal f(x) or -f(x) the function is neither even nor odd.

A: No, the number 50 is not an odd number - it is an even number.

The only function that is both odd and even is f (x) = 0. If a function is odd, the absolute value of that function is even. ... The product of two even functions is even.

symmetry: since tan(-x) = - tan(x) then tan (x) is an odd function and its graph is symmetric with respect the origin. intervals of increase/decrease: over one period and from -pi/2 to pi/2, tan (x) is increasing.

Answer: YES, 2 is in the list of numbers that are never perfect squares. The number 2 is NOT a perfect square and we can stop here as there is not need to complete the rest of the steps.

['Odd. End behavior go in different directions. If a function is positive, the left side of the graph will point down and the right side will point up (increasing from left to right). ... ', 'Straight line. Constant. Has a slope.']

Most functions are neither. In this case, as a real-valued function with a subset of the real numbers as its domain, the domain can't include any non-positive values. It's already true that the function can't be even or odd (unless it's regarded as defined over an empty domain (!), when it is both).

Explanation: A function f(x) is even if f(−x)=f(x) and function is odd if f(−x)=−x . Hence sin2(x) is an even function.

A one-to-one function is a function f such that f(a) = f(b) implies a = b. Not all odd functions are one-to-one. ... It is an odd function, because, for all x in the domain of f, -f(x) = f(-x) = 0. However, it is not a one-to-one function because f(a) = f(b) = 0 does not imply a = b, unless the domain contains only zero.

Odd numbers have the digits 1, 3, 5, 7 or 9 in their ones place. The sum of two odd numbers is always even. The product of two or more odd numbers is always odd.

The function cosh x has a Taylor series expression with only even exponents for x. Thus it is an even function, that is, symmetric with respect to the y-axis. The sum of the sinh and cosh series is the infinite series expression of the exponential function.

Floor & Ceiling don't have inverse functions as they tend to loose data while rounding up/down the input number. You may call them two alternate rounding functions, but they are not inverse/opposite to each other.

A: No, the number 80 is not an odd number - it is an even number.

The difference between two consecutive even and odd positive integers will be two, always. Eg. 5 -3 = 2. Here the smaller number is to be deducted from the smaller number.

A: No, the number 32 is not an odd number - it is an even number.

The only function which is both even and odd is f(x) = 0, defined for all real numbers. This is just a line which sits on the x-axis. If you count equations which are not a function in terms of y, then x=0 would also be both even and odd, and is just a line on the y-axis.
