Can a function be symmetric about the y-axis and the origin?

On the other hand, a function can be symmetric about a vertical line or about a point. In particular, a function that is symmetric about the y-axis is also an “even” function, and a function that is symmetric about the origin is also an “odd” function.

What functions are symmetric across the y-axis?

A function symmetrical with respect to the y-axis is called an even function. A function that is symmetrical with respect to the origin is called an odd function. f(x). Since f(−x) = f(x), this function is symmetrical with respect to the y-axis.

How do you find the origin of symmetry of a function?

For a function to be symmetrical about the origin, you must replace y with (-y) and x with (-x), and the resulting function must be equal to the original function. So there is no symmetry about the origin, and the answer is Symmetrical about the x-axis.

How do you find the symmetry of a rational function?

Test to see if the graph has symmetry by plugging in (-x) in the function. Options: If the signs all stay the same or all change, f(-x) = f(x), then you have even or y-axis symmetry. If either the numerator or the denominator changes signs completely, f(-x)= -f(x) then you have odd, or origin symmetry.

What does symmetric with respect to the y-axis mean?

Functions can be symmetrical about the y-axis, which means that if we reflect their graph about the y-axis we will get the same graph. There are other functions that we can reflect about both the x- and y-axis and get the same graph.

What is origin symmetry?

Symmetric about the Origin. Symmetric across the Origin. Symmetric with Respect to the Origin. Describes a graph that looks the same upside down or right side up. Formally, a graph is symmetric with respect to the origin if it is unchanged when reflected across both the x-axis and y-axis.

What is the y-axis?

A coordinate grid has two perpendicular lines, or axes (pronounced AX-eez), labeled just like number lines. The horizontal axis is usually called the x-axis. The vertical axis is usually called the y-axis. The point where the x- and y-axis intersect is called the origin.

How do you write the axis of symmetry?

The symmetry cuts any geometric shape into two equal halves. The axis of symmetry formula is given as, for a quadratic equation with standard form as y = ax2 + bx + c, is: x = -b/2a. If the parabola is in vertex form y = a(x-h)2 + k, then the formula is x = h.

Which graph is symmetric about y-axis?

A graph is said to be symmetric about the y -axis if whenever (a,b) is on the graph then so is (−a,b) . Here is a sketch of a graph that is symmetric about the y -axis. A graph is said to be symmetric about the origin if whenever (a,b) is on the graph then so is (−a,−b) .
