Question

let f:R to R be two functions defined by f(x)=[x],where [x] denotes the greatest integer less than or equal to x.Find (f not g)(5.75)&(g not f)(-root5). please answer this question fast​

Answer 1

f(x) = |x| , g(x) = [x]

fog(5/2) = |[5/2]| = |[2.5]| = |2| = 2

gof(root2) = [|root2|] = [root2] = [1.414] = 1

Answer 2

fοg(5.75)=f(5) =5  ∵[5.75]=5

gοf($-\sqrt{5}$)=g(-3)=-3   ∵[-2.23]=-3

Step-by-step explanation:

Given , f(x)= [x] and g(x) = [x]

fοg(5.75)=f(5) =5  ∵[5.75]=5

gοf($-\sqrt{5}$)=g(-3)=-3   ∵[-2.23]=-3
