is the absolute value of x function even or odd?

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.

It is indeed true that "whenever both x and −x are in the domain of the square root function the function values agree" because (as you know quite well) only x=0 satisfies that hypothesis. So according to the strict reading of the definition, the square root function is even.

The exponential function x is neither nor odd. Rather, An exponential function is a sum of an even and an odd fuction. The even fuction is known as cosh x and odd function is known as sinh x.

When we take the absolute value of a number, we always end up with a positive number (or zero). Whether the input was positive or negative (or zero), the output is always positive (or zero). For instance, | 3 | = 3, and | –3 | = 3 also.

Note: A function can be neither even nor odd if it does not exhibit either symmetry. For example, f(x)=2x f ( x ) = 2 x is neither even nor odd. Also, the only function that is both even and odd is the constant function f(x)=0 f ( x ) = 0 .

Odd functions have symmetry about the origin. thus xsinx is an even function.

Absolute Value Function Family If x = 0, then y = |0| = 0. If x is positive, then the function value is equal to x. ... Every absolute value graph will take this shape, as long as the expression inside the absolute value is linear.

A: No, the number 52 is not an odd number - it is an even number.

A function f is even if the graph of f is symmetric with respect to the y-axis. Algebraically, f is even if and only if f(-x) = f(x) for all x in the domain of f. A function f is odd if the graph of f is symmetric with respect to the origin.

The absolute value function is continuous (i.e. it has no gaps). It is differentiable everywhere except at the point x = 0, where it makes a sharp turn as it crosses the y-axis. A cusp on the graph of a continuous function.

Sine is an odd function, and cosine is an even function. You may not have come across these adjectives “odd” and “even” when applied to functions, but it's important to know them. ... A function f is said to be an even function if for any number x, f(–x) = f(x).

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.

The domain is all real numbers and the range is all positive numbers. The absolute parent function is f(x)=|x|. The domain, or values of x, can be any real number.

In mathematics, the absolute value or modulus of a real number x, denoted |x|, is the non-negative value of x without regard to its sign. Namely, |x| = x if x is positive, and |x| = −x if x is negative (in which case −x is positive), and |0| = 0.

Indeed x/x is only defined when x≠0. And wherever it is defined, its value is 1.

A function is even if f(−x)=f(x) f ( - x ) = f ( x ) . Check if f(−x)=f(x) f ( - x ) = f ( x ) . Since 1x2=1x2 1 x 2 = 1 x 2 , the function is even.

Sine is an odd function, and cosine is an even function. ... A function f is said to be an even function if for any number x, f(–x) = f(x). Most functions are neither odd nor even functions, but some of the most important functions are one or the other.
