dit : f(-4)?
f(-4) = (-4)²-2(-4)+3
= 16+8+3
=27 (a.)
14. dik: h(x) = 1/3x+8
h(a)= 24
dit: nilai a?
jawab : h(a)=1/3a+8=24
=1/3a=16
a=16x3=48
15.f(x) = ax+b
f(2) = 2a + b =1 ..1
f(-2) =-2a + b =-7 ..2
persamaan 1 - persamaan 2
4a=8
a=2
sub ke persamaan 1
2x2 + b = 1
4 + b = 1
b=1-4=-3
maka a=2, dan b=-3 (d.)
