a. ACTIVITY: Concept Note #2


Evaluation of Function - a process of calculating the value of a function (y )
for given values of x. The y is the dependent variable while x is the
independent variable. The process is done by substituting the numerical
values of x to the given function.

Example1: If f(x) = 4x2 – 2x + 4, find the value of each of the following:


a. f(2) d. x = -1
1
b. f ( ) e. f(2m + 1)
3
c. x = 0
4
Example 2: Given f(x) = ( ), find the following value:
x
a. f(1)
b. f(-1)
c. f(2x)

b. ANALYSIS
Evaluate the following function:
Given f(x) = x-2 , find the following values
a. f(0)
b. f(3)
c. f(x-1)

c. ABSTRACTION
1. What is evaluation of function?
2. What is the process in evaluating a function?

d. ASSESSMENT #2
1. Given f(x) = √ x−3, find the following values:
a.f(3) = √(3) – 3
f(3) =√(1.7) – 3
f(3) = -1.26794919243
b. f(4) f= √(4) - 3
f(4) = √(2) – 3
f(4) = -1
c. f(12)= √(12) - 3
f(12)= √(3.4) – 3
f(12)= 0.464101615138
d. f(x-3)
