Let \(f(x)=x^{3} .\) Evaluate each expression. $$f(0)$$

Short Answer

Expert verified
The value of \( f(0) \) is 0.

Step by step solution

01

Understand the Function

Given the function \( f(x) = x^3 \), it represents a cubic function where 'x' is raised to the power of 3. To find \( f(a) \) for any value 'a', we simply substitute 'a' into the function definition and compute \( a^3 \).
02

Substitute the Value of x

To evaluate \( f(0) \), substitute 0 for 'x' in the function \( f(x) = x^3 \). Thus, we have \( f(0) = 0^3 \).
03

Compute the Cubed Value

Calculate \( 0^3 \). Any number raised to the power of 3, where the number is 0, equals 0. Therefore, \( 0^3 = 0 \).
04

Write the Final Answer

The evaluation of \( f(0) \) is complete. The result of substituting 0 into the function is 0.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Function Evaluation
Function evaluation is a fundamental concept in mathematics. It involves finding the output of a given function for a particular input value. To evaluate a function like the cubic function given, start by identifying the variable in the function—here, it's "x" in the equation \( f(x) = x^3 \).
Next, determine the specific input or the value of "x" that you will substitute into the function. The process of function evaluation is essentially one of substitution. By replacing "x" with the chosen number, which in this case is 0, you can evaluate the expression \( f(0) \).
This substitution transforms the function into \( 0^3 \), which can then be simplified to find the result. Through this evaluation, the expression provides the corresponding output of the function for this particular input. In general, function evaluation allows us to understand how changing the input affects the output and is a critical step in analyzing mathematical models.
Exponentiation
Exponentiation is the mathematical operation involving two numbers, the base and the exponent. The concept indicates how many times the base is multiplied by itself. In the case of the function \( f(x) = x^3 \), the base is "x," and the exponent is 3, which means "x" is multiplied by itself twice more in addition to the original "x."
In this particular example, we substitute 0 for "x" to evaluate \( 0^3 \). When 0 is the base, no matter what the exponent, the result of exponentiation is always 0. This is a straightforward case where exponentiation simplifies to the simplest possible form.
Keep in mind that the rules of exponentiation extend beyond whole numbers and such simple cases to more complex scenarios involving fractional exponents or negative bases, but in the context of this evaluation, it's crucial to understand the basic mechanism of repeating multiplication.
Polynomial Functions
Polynomial functions are expressions consisting of variables raised to whole-number exponents. Such functions are named based on their highest degree. A cubic function, like the one given, is a specific type of polynomial function where the highest exponent is 3.
Understanding polynomial functions involves examining factors such as the degree, the coefficients of the terms, and their individual impacts on the overall function's shape when plotted. These functions can demonstrate a wide range of behaviors depending on those factors.
Cubic functions, for example, generally exhibit an "S" shaped curve when graphed. They can have one or more turning points, and the sign of the leading coefficient influences the direction of the curve's ends. This exercise focuses on the expression \( x^3 \) without additional coefficients or terms, representing one of the simplest forms of a polynomial function.
By mastering the fundamental evaluation of such functions, you can start to tackle more complex polynomial expressions and their real-world applications.
