people are related?
2. What qualifies for two
people to have a relation?

Relations and functions:
 Relations are made up of two groups, both with at least
one object in them that are connected by some
characteristic or rule.
 Use arrows to show connections between pairs of
objects between groups.
 Emphasize that in writing ordered pairs, the elements
must be written in a strict order: (first group, second
group).
 All functions are relations, but not all relations are
functions.
RELATION - A set of one or more
ordered pairs
have all elements in the first group
paired with exactly one object in the
second group (one-to-one relation). If an
element in the second group is paired
with two or more objects in the first
group, it can still be a function provided
that the first statement is still followed
(many-to-one relation).
FUNCTIONS

NANAY TATAY
MILAGROS ERNESTO
TERESA RUDY
MAUREEN JUN
This is an example of a
function because each
person has exactly one
partner. Moreover, this
illustration shows a one-to-
one function because for
every one nanay, there
corresponds only one tatay
from the second group.
CHILDREN FATHER

Marianne
Joseph
Lando
Kenneth
Children-to-parent
In addition, this illustration
shows a many-to-one function
because there are more than
one child that has one tatay.
For instance, Diane and
Marianne connect to Manny as
their tatay. Similarly, Joseph
and Kenneth connect to Tatay
Lando.
One-to-many and many-to-
many relations cannot be
functions and are simply
referred to as RELATIONS.

This illustration shows a one-
to-many correspondence
because Lola Basyang
connects to more than one
grandchildren (Jose, Tinay,
Pedro, and Mutya).
• Recall equations in two
variables 𝑥 and 𝑦. Give some
simple examples of these
equations such as:
𝑦 = 𝑥 + 1 𝑦 = 𝑥 + 3 𝑦 = 𝑥 − 5
Evaluating functions:
• Recall substitution of a value in x to
get the value of 𝒚.
Using 𝑥 = 1,
𝑦 = 𝑥 + 5
𝑦 = 1 + 5
RESULT
𝑦 = 6
Evaluating functions:
Using 𝑥 = 2,
𝑦 = 𝑥 + 5
𝑦 = 2 + 5
RESULT
𝑦 = 7
Evaluating functions:
Using 𝑥 = 3,
𝑦 = 𝑥 + 5
𝑦 = 3 + 5
RESULT
𝑦 = 8
Evaluating functions:
Explain that equations are also
relations of numbers relating 𝒙
and 𝒚.

Imagine that we are processing the numbers, as shown below, by
substituting each value in place of x:
1 + 5
2 + 5
3 + 5
APPLICATIONS
II. Instructions: Determine the value of y by
replacing x in each equation with the given
value.
1. y = 8x - 10 x = 6
2. y = −3x + 5 x = −1
3. y = 15 − 8x x = 4
4. y = 2 + 7x x = 1
5. y = -9x − 100 x = −10
