Function is a technical term that is used to symbolize the relationship between two variables.
Y = f (x) = x + 2

You can find out the relationship between two real variables.
Such as:
You can find out the relationship between cost and revenue
You can find out the distance through a function of time and speed
You can find out the relation between Time and Labor
You can Find out the relationship between Time and units of production
You can find out the profit through a function of loss
You can find out the quantity demanded with a function of price

Distance covered is a function of time and speed
The railway freight changed is a function of weight or volume
The quantity demanded is a function of price
The product supplied is a function of demand

Limit :Limit : The limit of a function is that fixed value to which a function approaches as the variable approaches a given value. The function approaches this fixed constant in such a way that the absolute value of the difference between the function and the constant may be made smaller and smaller than any positive number,
however small.
Continuity: Continuity: A function f(x) is said to be continuous at x=a, if corresponding to any arbitrarily assigned positive number, however small there exists a positive number

You can find out the linear relationship between two variables
Such As:
You can find out the linear relationship between investment and annual income
You can find out the relationship between cost and number of unites produced
You can find out constant expenses and variable expenses
You can use it on decision making
You can determine total production of investment
You can find out the slope of a line

When number of unit produced increases from 4000 to 6000, the total cost of production increases from 22,000 to 30,000 TK. Find the relationship between cost and the number of units produced.
y – y1 = m (x – x1)
Solution:
Here,
Y1 = 22,000Y2 = 30,000X1 = 4,000X2 = 6,000And,m = (Y2 - Y1) / (X2 - X1)

A system of geometry where the position of points on the plane is described using an ordered pair of numbers.
Quadrants: The two directed lines, when they intersect at right angles at the point of origin, divide their plane into four parts or regions. These four parts are known as quadrant.
Coordinates: In a two dimensional figure, a point in plane has two coordinates. The first coordinate is known as x-coordinate and second coordinate is known as y-coordinate.

Coordinates of mid point: Coordinates of mid point: We can find out the coordinates of a mid point from the coordinates of any two points using the following formula:

:int 1212 yyxxpoMid
Distance between two points: Distance between two points: The distance, say d, between two points P(x1, y1) and Q(x2, y2) is given by the formula:

If you know the coordinates of a group of points you can:
calculate the midpoint of a line segment. plot points the points calculate the distance between two points. calculate the median and mean of a data
set. describe how mathematical modeling can be
used in decision making.
