Answer:
Its a i just took the test
Step-by-step explanation:
I^63
=i*(i^(2*31))
=i*(i^2)^31
i^2=-1
=(-1)^31*i
=-1*i
=-i
Ok so function means that x never repeats with a different y
function could be
table: (1,2) (2,4) (4,8) etc
graph the points
not a function could be
(1,1) (2,1) (3,1) (4,1)
range is the output or y
range is R={-4,-1,2,5}
