This problem shows that infinite sets behave differ- ently than the finite ones considered in the previous problem. (i) find a function f: z-> z that is injective, but not surjective. (ii) find a function g: zz that is surjective, but not injective. - (iii) find a proper subset s of z (that is, s is not z itself) and a bijective function h: sz.

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer
