Question

G) ( f: R rightarrow R quad f(x)=left{begin{array}{l}x(x)-4, x in Q x|x|-sqrt{3}, x in thetaend{array}right. )
(B) Will be correct because ( a+x-2 ) and ( x=(3) 4 )
[
begin{array}{l}
f(2)=2(21-4=0
fleft(3^{4}right)=left(3^{4}right)left(3^{2}right)-sqrt{3}=0
f(2)=f((a))
end{array}
]
So many one
& range of ( x|z|-4 ). will be bilong to all real number
[
begin{array}{l}
text { as por } n<0,-x^{2}-4 Rightarrow-infty
qquad F(x)>0, x^{2}-4 Rightarrow-4 leq x^{2}-4 leq infty
end{array}
]
So mto function. Cive yours feed bask ( 930610993 )

# 61. Iff:R → R. f(x)= XX-4 XE then f(x) is 1x1x1-3 x¢Q' (A) one to one and onto (B) many to one and onto (C) one to one and into (D) many to one and into
