Jawaban:
Diketahui
f(6) = 6
f(40) = 40
Ditanya persamaan fungsi linear?
Jawab
f( x ) = ax + b
f(6) = a(6) + b
6 = 6a + b
f(40) = a(40) + b
40 = 40a + b
40a + b = 40
6a + b =. 6 -
34a = 34
a = 34/34
a = 1
6a + b = 6
6(1) + b = 6
6 + b = 6
b = 6-6
b = 0
maka persamaan fungsi liniernya
f(x) = ax + b
f(x) = (1)x + 0
f(x) = x
Jadi persamaan fungsinya adalah f(x) = x
Semoga membantu dan tidak keliru
