Question

Help kak ga ngerti please ya

Answer 1

F(1)=2
f(-3)=1
f(7)=-4
x=1
a=-11

Answer 2

A) f(1) = 6 / (5-1) = 8/4 = 2
b) f(-3) = 8/ (5+3) = 8/8 = 1
c) f(7) = 8 / (5 - 7) = 8/-2 = -4
d) f(x) = 2
     8 / (5 - x ) = 2
     8 = 2 (5 - x)
     8 = 10 - 2x
     8 - 10 = - 2x
       - 2 = - 2x
           x = 1

e) f(a) = 0,5
     8 / (5 - a) = 1/2
      16 = 10 - 2a
        6 = -2a
        a = -3
