Question

Its a function or not fuction?​

Answer 1

answer:

it's a function

step-by-step explanation:

according to g00gle- in mathematics, a function is a binary relation between two sets that associates to each element of the first set exactly one element of the second set. typical examples are functions from integers to integers, or from real numbers to real numbers.

but the simple definition is that a function is when the x value isn't being repeated. and since in your case it isn't, the table is a function

another way to solve-

for this, we will put the pairs into a graph then perform the line test-

as you can see each point has its own individual line, therefore, meaning it passed the vertical line test

good luck :)

i hope this helps

brainliest would be highly appreciated

have a nice day!

Answer 2

Answer:

This IS A FUNCTION

Step-by-step explanation:

You can determine is a graph or chart is a function IF the x value gives off ONE y value

So in other words, an x value is matched up with one y value. There CAN be more than one x value with y though.

EXAMPLE.

If -3 = 3 and 0 = 3, this is a function

If 4 = 1 and 4 = 2, this is not a function
