Question

Ditentukan fungsi 9 : x _> 5x-8 a.tulislah rumus fungsi 9 b.tentukan nilai fungsi 9 u\x=-2 c.jika f (c)=19 tentukan nilai c d, tentukan nilai f (-1), f(d) ,f(2)

Answer 1

A.  g(x) = 5x - 8
b. g(-2) = 5(-2) - 8 = -10 - 8 = -18
c. f(c) = 19
     5c - 8 = 19
     5c = 27
       c = 27/5
d. f (-1) = 5 (-1) - 8 = -5 - 8 = -13
    f(d) = 5(d) - 8 = 5d - 8
   f(2) = 5(2) - 8 = 10 - 8 = 2
