Step 1: Determine the graph's end behavior.
Step 2: Find the x-intercepts or zeros of the function.
Step 3: Find the y-intercept of the function.
Step 4: Determine if there is any symmetry.
Step 5: Find the number of maximum turning points.
Step 6: Find extra points, if needed.
Step 7: Draw the graph.

1 Circle
set of all points on a given plane that is equidistant from
a fixed point on the plane called the center of the circle;
named based on the letter used to indicate the center of
the circle

““An electronic and communication
engineer designed a circular disk to be put
up in DJAPMNHS’ campus for
communication purposes in the whole
Division of Batangas. Before he installs the
disk, he left his men check the disk and its
parts. Supposed I am the engineer and you
are my working men, what are now the
parts of the circular disk? Identify the
radius, chord, diameter, secant and tangent
given the figure.”
37. Abstraction/Generalization
Circle
set of all points on a
given plane that is
equidistant from a fixed
point on the plane called
the center of the circle
Radius
distance between the
center of the circle and
a point on the circle; the
plural form of radius is
radii
Diameter
a chord that passes
through the center of
the circle; the diameter
is also the longest chord
in a circle
Chord
a line segment whose
endpoints lie on the
circle
Secant
a line that intersects a
circle in two points
Tangent
a line that intersects a
circle at only one point;
the point where it
intersects the circle is
called the point of
tangency

Let’s Practice!
On a ¼ sheet of paper, draw a circle with
center B, with two diameters namely
segments AC and DF, whose chords are
AC, DF, CF, and DG, a secant HI, and
tangent JK intersecting at point A.

(Journal Writing)
Circles are still symbolically important today.
They are often used to symbolize harmony and
unity. As a person, how can you promote
harmonious relationship to your family, school
and community. Write a short essay about this
and create a unity symbol of your own using
circles. Then, post it in your personal Facebook
account with the #ilovemath.
