Is this mapping a function or not a function ¿ i’ll mark brainlist

Not a function

Step-by-step explanation:

If it is a function, every input has only one output. Meaning if we graph it, it will pass the vertical line test.

If you want to think about it in x and y, all values of x can only correspond to one value of y.

In this case, we can see that the x-value 6 has 2 corresponding y-values (5 and 10), therefore, this mapping is not a function.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
