A function f is defined on set of natural no as f(x)={ x2 if 1 ≤1 5 - Maths - Relations and Functions

Question

A function f is defined on set of natural no as

f(x)={ x2​ if 1 ≤1 < 5
{ x + 3 if 5 < x ≤ 8
{x-3/2 if 8 <x≤ 11

Write function in roster form and also find domain and range of the
function

Hi, fx= y=x2 if 1≤x<5R = 1,1,2,4,3,9,4,16so domain = 1,2,3,4Ramge = 1,4,9,16second fx=y= x+3 if 5<x≤8R  = 6,9,7,10,8,11domain = 6,7,8range  = 9,10,11similarrly try last part for your practice
