Question

find the domain & real function
f(x)= √9-x2
​

Answer 1

Answer:

Step-by-step explanation:

√9-x^2

=3-x^2

now domain  is R-(√3)

all real number except √3 because domain is

where the fuction has value and when √3 is put in equation then ans beacomes aero means at √3 the fuction can not defined  hence ans should be    

  R-(√3)
