## Which of the 12 basic functions are even functions?

Which of the 12 basic functions is an even function? Even Functions: The squaring function and the absolute value function. Odd Functions: The identity function, the cubing function, the reciprocal function, the sine function. Neither: The square root function, the exponential function and the log function.

## What are the basic functions?

Here are some of the most commonly used functions, and their graphs:

- Linear Function: f(x) = mx + b.
- Square Function: f(x) = x2
- Cube Function: f(x) = x3
- Square Root Function: f(x) = √x.
- Absolute Value Function: f(x) = |x|
- Reciprocal Function. f(x) = 1/x.

## What basic functions are bounded?

If f is real-valued and f(x) ≤ A for all x in X, then the function is said to be bounded (from) above by A. If f(x) ≥ B for all x in X, then the function is said to be bounded (from) below by B. A real-valued function is bounded if and only if it is bounded from above and below.

## What are the 8 parent functions?

The following figures show the graphs of parent functions: linear, quadratic, cubic, absolute, reciprocal, exponential, logarithmic, square root, sine, cosine, tangent. Scroll down the page for more examples and solutions.

## What three basic functions are even?

Even Functions: The squaring function and the absolute value function. Odd Functions: The identity function, the cubing function, the reciprocal function, the sine function.

## Which functions are odd functions?

A function with a graph that is symmetric about the origin is called an odd function. 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.

## What are the 10 basic functions?

Terms in this set (10)

- y=x^2. Squaring.
- y=x^3. Cubing.
- y=|x| Absolute Value.
- y=1/x. Reciprocal.
- y=sin(x) Sine.
- y=cos(x) Cosine.
- y=e^x. Exponential Growth.
- y=ln(x) Natural Log.

## What functions are bounded below?

Definition: A function f is bounded below if there is some number b that is less than or equal to every number in the range of f. Any such number b is called a lower bound of f.

## How do you find a basic function?

Plot points to determine the general shape of the basic functions. The shape, as well as the domain and range, of each should be memorized. The basic polynomial functions are: f(x)=c, f(x)=x, f(x)=x2, and f(x)=x3. The basic nonpolynomial functions are: f(x)=|x|, f(x)=√x, and f(x)=1x.
