Quiz
Question 1: What` s this?
What is function?
y is called a function of x when
for each value of x, we always identify only once corresponding value of y, then, and x is called variable.
Quiz
Question 2:
Which function is the increasing function?
When the value of x is increasing,
the corresponding value of y (or f(x)) is increasing then f(x) is called the increasing function.
When the value of x is increasing,
the corresponding value of y (or f(x)) is decreasing then f(x) is called the decreasing function.
