• What is affected by the numerical
coefficient that is multiplied to the
quadratic term?
• What is affected by the value of the
constant term of a quadratic function?
• Describe the relation between the
multiplier of the quadratic term to the
width of the parabola.
• The function y=2𝑥2 is translated 4 units
upward. What is the new function?
• The AOS of y=𝑥2is moved to x=3 and no
change in the value of y. What is the
new function?
INTRODUCTION TO RADICALS
• What are radicals?
• What are the parts of a radical?
• How do you transform a radical into
fractional exponent form?
WHAT ARE RADICALS BASICALLY?
Radicals
• Irrational Numbers expressed in roots.
• Another way to express numbers with
fractional exponents
• Expressed as: 𝑎𝑛 where n=index and
a=radicand
• Example: 3 93
Parts of a radical
Exercise
• Identify the radicand and the index of
the radical in the following:

• 84
• 𝑥𝑦𝑧𝑛 (where n is a natural number
greater than 1)
