## What is the domain of x 3x?

Algebra Examples The domain of the expression is all real numbers except where the expression is undefined.

## What is the domain of f/x )= x 3 x 3?

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. The range is the set of all valid y values. Use the graph to find the range.

**How do you find the domain of a function x 3?**

For the cubic function f(x)=x3 f ( x ) = x 3 , the domain is all real numbers because the horizontal extent of the graph is the whole real number line. The same applies to the vertical extent of the graph, so the domain and range include all real numbers.

**How do you find the domain and range of a solution?**

How to Find The Domain and Range of an Equation? To find the domain and range, we simply solve the equation y = f(x) to determine the values of the independent variable x and obtain the domain. To calculate the range of the function, we simply express x as x=g(y) and then find the domain of g(y).

### What is the domain and range of x 3?

x3 is a polynomial, which means its domain is R , and in our case, its range is also R because the only root that x3 has, 0, is not a double root (technically it’s a triple root, and because 3 is odd, the function switches sign).

### What’s the inverse of 3x?

Answer: The Inverse of y = 3x is f-1(x) = 1/3x.

**What is the domain for 3x 3?**

The domain of the expression is all real numbers except where the expression is undefined.

**What is the domain of the function 3 x 3?**

The domain of the function f(x) = 3×3 is {2, 5}.

#### What is the domain of MOD x 3?

Observe that in y=|x−3|,x can any value from R . Hence, Domain is R . Also, ∀x∈R,|x−3|≥0 .

#### How do you find the domain of x 2 3?

By definition, x2/3=3√x2. Since we can compute x2 for any real number x, and since we can compute a cubic root for any real number, whether it be positive, negative, or zero, the domain is all real numbers. On the other hand, as Kannappan hints, the range of this function is [0,∞).

**How do you find the domain of x^3 in Algebra?**

Algebra. Find the Domain and Range y=x^3. y = x3 y = x 3. The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. Interval Notation: (−∞,∞) ( – ∞, ∞) Set -Builder Notation: {x|x ∈ R} { x | x ∈ ℝ }

**What is the domain of the square root function?**

This a linear (polynomial) function and its domain is. This a composed square root function. The domain is found by solving the inequality The given function is a rational function. Its domain is the set of all real numbers except those values of x that make the denominator zero.

## What is R2 and R3 in linear equations?

Linear Equations in Three Variables. R2 is the space of 2 dimensions. There is an x-coordinate that can be any real number, and there is a y-coordinate that can be any real number. R3 is the space of 3 dimensions. There is an x, y,andz coordinate. Each coordinate can be any real number.

## What does R3 stand for in math?

R3is the space of 3 dimensions. There is an x, y,andz coordinate. Each coordinate can be any real number. Linear equations in three variables If a, b, c and r are real numbers (and if a, b,andc are not all equal to 0) then ax + by + cz = r is called a linear equation in three variables.
