x | y
-
2 | 10
4 | 20
6 | 30
just plug the x values (2,4,6) into x in the equation and you get your y! example would be y=5(2) so y=10
Answer:
16
Step-by-step explanation:
The average rate of change formula is 
(-2-5)/(6-(-1))=-1
I^32 = (i^4)^8 and i^4 = 1
so (i^4)^8 =1^8 = 1
The trick on all questions like this is to get as many i^4’s out of the way, since they’re all just 1s.
