Graphs of Simple Function

Here we will learn about the graphs of simple functions that is multiples of different numbers.

The example will help us to understand the graph of multiples of different numbers.

1. Draw the graph of the function y = 3x. 

2. From the graph, find the value of y, when 

(a) x = 4        

(b) x = 5

Solution: 

1. The given function is y = 3x. 
For some different values of x, the corresponding values of y are given below. 

        x              0            1             2             3      
y = 3x
0
3
6
9

On a graph paper plot the points O (0, 0), A (1, 3), B (2, 6) and C (3, 9) and join them successively to obtain the required graph.

Graphs of Simple Function

2. Reading off from the graph of simple function:

(a) On the x-axis, take the point L at x = 4.

Draw LP ⊥ x-axis, meeting the graph at P.

Clearly, PL = 12 units.

Therefore, x = 4 ⇒ y = 12.

(b) On the x-axis, take the point M at x = 5.

Draw MQ ⊥ x-axis, meeting the graph at Q.

Clearly MQ = 15 units

Therefore, x = 5 ⇒ y = 15
