Which is true regarding the function?

F (-6)=10 is true about the function 
f (x) stands for y 
and x stands for X 
So when you plug in the numbers they should be able to hold true 

{(8, –3), (0, 4), (1, –5), (2, –1), (–6, 10)}

f (-3)=8 this is not true because there is no x=-3 In the function, this is NOT representing (8,-3) it is representing (-3,8)

f (3)=5 this is not true because there is no x=3 In the function, this is representing (3,5)

f (8)=0 this is not true because when x=8 In the function equals to f(8)=-3 not 0, this represents (8,0)

f (-6)=10 this is true because when x=-6 in the function f (-6)=10 this does represent (-6,10) in the function  hope its help
