Question

4.1) Define modulus function and draw a rough graph of modulus function (2) ii) If f(x)=2x-3 find f(1) and f(0) ​

Answer 1

A function which always gives a non negative real value irrespective of the input values is called a modulus function.

It is given as

f(x)=∣x∣={

x,x≥0

−x,x<0

Henc the graph of f(x)=∣x∣.
