Can someone please help me find the answer to this question I’m very confused

What should i do if the cables are not secure

Explanation:

Because if you were doing this for the first time, and the cables were loose (this is pretty common) the person who made the instructions should have an answer to it on the instructions.

. a function is a relation in which each input has only one output. in the relation , y is a function of x, because for each input x (1, 2, 3, or 0), there is only one output y. x is not a function of y, because the input y = 3 has multiple outputs: x = 1 and x = 2.
