Question

Diketahui suatu fungsi linear f(x) = 2x + m, bentuk fungsi tersebut jika f(3) = 4 adalah

Answer 1

F (x) = 2x + m
f (3) = 2(3) + m
= 6 + m

6 + m = 4
m = 4 - 6
m = -2

bentuk fungsinya :
f (x) = 2x + m
f (x) = 2x - 2

Answer 2

f(x) = 2x + m
f(3) = 2(3) + m = 4
6 + m = 4
m = 4 - 6
m = -2
maka f(x) = 2x + m
f(x) = 2x - 2
