Jika f(x) = 9x +( a + 6 ) dan f (1) = 16, tentukan nilai a dan f (2).

Dik, f (x) = 9x + (a+6)...
dan f(1) = 16, berapa a dan f(2) ?
masukan....
f (1) = 9 + a + 6 = 16
=> a = -9-6+16
=> a= 1
berapa f(2) ?
f (2) = 9(2) + (1+6)
= 18 + 7 = 25
makasih

Jawaban ..
F(1) =9.1+(a+6)=16
=9+(a+6)=16
=a+(9+6)=16
=a+15. =16
a=16-15
a=1
F(2)=9.2+(1+6)
= 18 +7 = 25

Jdi a =1,
f(2)=25

Maad klo salah ,smga brmnfaat :)
