Answer:
Step-by-step explanation:
Given that g is a function from g : {1, 2, 3} ->{1, 2, 4, 8}
by the function

i.e. we have 
Range = {2,4,8} Since there is an extra element 1 in the co domain which is not in range , g is not on to
But g is one to one as 1,2,3 have different images.
No, because the input repeated 4 twice and the output repeated 3 twice
Step Number 1. is to Simplify

Step Number 2. <span>Simplify so you get </span>

Done! :)
52=x because x+128=180 and that is a 189 angle
