Question

I already answered some but I believe they're wrong. Can someone please check and help with the last 2?

For eac h below, state whether it represents a function Graph 1 Graph 2 Graph 3 4 4 27 2 -8 -6 2 4 6 -2 -2 4 -6 Function? Yes No Yes No Yes No Graph 4 Graph 6 Graph 5 2- -2 -4 2 -2 -1 -2 Function? Yes Yes No No Yes No

Answer 1

graph so nat - 4 a has two images ie -34-5 function Aus- 2 (Not) graph-3 Some point has a simage beat other than not a Image of domain points not exist thats why it is also not a function. Aess (No) graph. 4 All the domain point has a unique Image ie each & every element of domein cassign a unique element Ang & Yes as y graph-5 Ans Same (yes)

By the given information. I have to Check with provided graph it is function, or not By the def of functions het A fb aree Awo non-empty sets, now define a suele f' from A to B , which assigns every element of domain A has a unique image with the element of Co-domain B. then this f is belbed function form A to B. Now In graph (1) . 1ot Explenation & graph inersect at a single point with vertical two times, 1 – 4 is not map uniquely has a Images so it is not function, Similarly (-2, 0) has no unique image so need a function Ans (Not)

graphs + to os in Co-domain for to be element domain has 0 ha tovo images function, each & every onial image, Ans (No)
