Unit I
Que. 1 (a) Using Illustrations, explain the following:
I. Linear and non - Linear functions
II. Absolute and Inverse functions
Solution :
(i) Linear and non - Linear functions
Linear functions: When the variable are linearly dependent and the graph of the function is straight line
( ) a , a linear function
e.g.
y = 2+3x is the equation of linear function
the graph of this equation is straight line.
x 1 2 3 4
y =2+3x 5 7 11 14
Non – Linear Functions :
The functions which are not linear are called non linear functions. A quadratic or parabolic
function is called non – linear functions .
Equation of such type of functions are given below
