Percentage
A percentage is a number indicated as a fraction of 100. It is a dimensionless number often expressed using the symbol %.
Algebraic Expressions
In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.
Numbers
Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.
Subtraction
Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.
Addition
Before we begin to understand the addition of algebraic expressions, we need to list out a few things that form the basis of algebra.
![**Finding f(7):**
In order to determine the value of f(7), we refer to the given diagram. This diagram is known as a function mapping diagram, which visually represents how each element from the domain (the set of input values on the left) is associated with an element in the codomain (the set of output values on the right).
In this specific diagram:
- The domain (left oval) contains the values: 7, -4, and 6.
- The codomain (right oval) contains the values: -3, 0, and 7.
The arrows indicate the mapping of each element in the domain to an element in the codomain according to the function \( f \). Here’s the mapping detail:
- The element 7 is mapped to -3.
- The element -4 is mapped to 0.
- The element 6 is mapped to 7.
By inspecting the mapping for the element 7 in the domain, we see that it is connected by an arrow to the value -3 in the codomain.
Therefore, the value of f(7) is:
\[ f(7) = -3 \]
**Answer:**
\[ f(7) = \boxed{-3} \]](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0bf6a450-468f-442a-9842-abd5e4c441a8%2F8836bb20-7d65-4d63-9b42-0f146c205bd4%2Fnng6cc_processed.png&w=3840&q=75)
