Question

There's a function table and they want me to find the missing value. It looks like this:

x y
-2 3
-1 0
0 -1
1
2 3

I also need help figuring out what the function is between them. If you have a specific method, please share. It's really hard to grasp for me :(

Answer 1

lets say your function varies like y=k*x , where k is constant
now put y= 3, x=-2 to find k
3=k*-2
k=-2/3 there you have the constant
now in next case you have
x=1, k= -2/3 but y= ?
plug in the values
y=-2/3*1=-2/3

Answer 2

and your required function is \[y=\frac{ -2 }{ 3 }x\]

Answer 3

Thank you so much for your help!
