Question

Ditentukan fungsi f : x > 2 pangkat x +1
a.tentukan f(1),f(2),f(3),dan f(4)
b. jika diketahui f(c)=65,tentukan c


Kalau Yg Jawab Anaak Allah

Answer 1

A. f(1) = 2¹+1=2+1=3
f(2) = 2²+1=4+1=5
f(3) = 2³+1=8+1=9
f(4) = 2⁴+1=16+1=17

b. f(c) = 2^6+1=64+1=65
nilai c = 6

Answer 2

F(x) = 2^x +1

a. f(1) = 2^1 + 1=2^1=3
   f(3) = 2^3 +1 =8+1 =9
   f(4) = 2^4 + 1 = 16 +1  =17
b. f(c) = 2^c  + 1
   65  = 2^c +1
   2^c = 64
       c= 6
