Express the function (or rule) in words. $$g(x)=\frac{x}{3}-4$$

Short Answer

Expert verified
Take one-third of the input number and subtract 4.

Step by step solution

01

Analyze the Expression

First, let's break down the function \( g(x) = \frac{x}{3} - 4 \). We have a variable \( x \) divided by 3 and then 4 is subtracted.
02

Describe the First Operation

Identify the initial operation applied to \( x \). The variable \( x \) is divided by 3. So, the function starts with taking one-third of the input \( x \).
03

Describe the Second Operation

After dividing \( x \) by 3, the function then subtracts 4 from the result. This gives the final output of the function.
04

Combine the Description

Combine both operations into a single descriptive sentence: The function takes one-third of a number and then subtracts 4 from it.

Key Concepts

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

Mathematical Expressions
A mathematical expression can be likened to a recipe or formula in math language. It's composed of symbols, numbers, and operations that combine to represent a particular concept or value without an equality sign. Consider the expression \( \frac{x}{3} - 4 \). It includes the variable \( x \), which acts like a placeholder for any number you might substitute in. This specific expression outlines how to modify the given \( x \) through division and subtraction. The division by 3 and then the subtraction of 4 are the operations that dictate the "recipe" for calculating this expression. When reading or writing a mathematical expression, it helps to know what each part signifies:
  • **Variables**: Such as \( x \) in our expression, stand in for values we can change.
  • **Constants**: Like 3 and 4, which are fixed values.
  • **Operations**: These contain actions like division (\( \div \)) and subtraction (\( - \)).
Connecting these elements correctly helps us interpret the statement and perform the necessary calculations.
Algebraic Functions
Algebraic functions are expressions that use algebraic symbols and operations, relating variables to one another in a specific way. When we talk about functions like \( g(x) = \frac{x}{3} - 4 \), we're referring to a rule that connects each input \( x \) to exactly one output. Let's break it down to understand better:
  • **Input/output relationship:** The input\( x \), once substituted into the function, is processed systematically to yield an output.
  • **Function Notation:** Typically, we use notations like \( g(x) \) to signify the function, where \( g \) is simply the name of the function.
  • **Computation:** For the function \( g(x) \), first we divide the input by 3, then subtract 4. This gives us the final numerical outcome for any given \( x \).
Understanding algebraic functions helps in mapping a comprehensive view of how changes in input affect the resulting value.
Step-by-Step Solution
When faced with a function like \( g(x) = \frac{x}{3} - 4 \), explaining how to express it in words can be simplified through a step-by-step approach. This breaks the problem down into manageable tasks.1. **Analyze the Expression**: Here, you should look into each part of the expression. We see \( x \) is involved in two main operations — division by 3 and subtraction by 4. This analysis lets us understand which mathematical operations are involved. 2. **Describe Operations Individually**: First, recognize that \( x \) is divided by 3. This gives a clue that for any input \( x \), you are calculating a third of it. Next, note that 4 is subtracted. So, from our earlier division result, there's a subtraction happening. 3. **Combine the Description**: Lastly, wrap up these observations familiarly: "The function takes one-third of a number and then subtracts 4 from it." This amalgamation neatly converts the equation into an understandable verbal rule.Approaching the solution in steps makes it easier to digest, especially for complex problems. Each step builds upon the previous, crystallizing our understanding without suddenly overwhelming details.

Revenue, Cost, and Profit A print shop makes bumper stickers for election campaigns. If \(x\) stickers are ordered (where \(x<10,000\) ), then the price per sticker is \(0.15-0.000002 x\) dollars, and the total cost of producing the order is \(0.095 x-0.0000005 x^{2}\) dollars. Use the fact that revenue \(=\) price per item \(\times\) number of items sold to express \(R(x),\) the revenue from an order of \(x\) stickers, as a product of two functions of \(x .\)
