Question

Me ajuda por favorrrr

Answer 1

35-

a)

g(f(2))=g(2²-1) =g(3)=2*3+1=7

b)

f(g(2))=f(2*2+1)=f(5)=5²-1=24

c)

f(f(1))=f(1²-1)=f(0)=0²-1=-1

d)

g(g(-3))=g(2*(-3)+1)=g(-5)=2*(-5)+1 =-9

36-

a)

f(2*10+3)=f(23)=23+1=24

b)

g(-1+1)=g(0)=2*0+3=3

37-

g(√2)=√2/2

f (g(√2)) =f(√2/2)=-6√2/2=-3√2

38-

a)

g(g(1)) =g(5)=5/5=1

b)

g(f(2))=g(7)=5/7

c)

f(f(-1))=f(1)=2+3=5

d)

f(g(3))=f(5/3)=10/3+3=19/3

e)

f(25/2) =25+3=28

f)

f(g(-1/9))=f(5/(-1/9))=f(-45)=-90+3=-87
