f : A -> B didefinisikan f(x)=x² + 9 dengan A={-3,-2,0,1,2}. tentukkan range fungsi f!

- f(x) = x² + 9
f(-3) = (-3)² + 9
= 9 + 9
= 18
- f(x) = x² + 9
f(-2) = (-2)² + 9
= 4 + 9
= 13
- f(x) = x² + 9
f(0) = (0)² + 9
= 0 + 9
= 9
- f(x) = x² + 9
f(1) = (1)² + 9
= 1 + 9
= 10
- f(x) = x² + 9
f(2) = (2)² + 9
= 4 + 9
= 13

semoga bermanfaat
