The document explains the concept of the domain of a function, defining it as the set of all possible input values (x) that do not make the function undefined. It provides examples of various functions, detailing their specific domains, such as f(x)=9/x, where x cannot equal zero, and f(x)=1/(x^2 – x - 2), which excludes -1 and 2. The summary highlights that the domain can vary based on the function's mathematical restrictions.

GENERAL MATHEMATIC 11

2. WHAT IS THE DOMAIN OF THE
FUNCTION?
The set containing all possible values that
may be used as arguments of a function.
A set containing all values of x or the
abscissa.
Set of all values of x which do not make the
function undefined

3. DOMAIN OF THE FUNCTION
F(x)= 2x+7
Set all real number

4. DOMAIN OF THE FUNCTION
F(x)= x/5
Set all real number

5. DOMAIN OF THE FUNCTION
F(x)= 9/x
Set all real number such that
x should not be equal to zero.

6. DOMAIN OF THE FUNCTION
F(x)= 9/(x+2)
Set all real number such that
x should not be equal to -2.

7. DOMAIN OF THE FUNCTION
F(x)= 1/(x^2 –x-2)
Set all real number except -
1and 2.

8. DOMAIN OF THE FUNCTION
F(x)=
Set all real number such that
z is greater or equal to -5.
