We are given rule
when
input is (x,y)
then output is (x+7 , y-3)
(A)
we are given
input is (-10,0)
so, x=-10 and y=0
now, we can find output
x+7=-10+7=-3
y-3=0-3=-3
so, output is (-3,-3)
(B)
we are given
input is (-7,3)
so, x=-7 and y=3
now, we can find output
x+7=-7+7=0
y-3=3-3=0
so, output is (0,0)
(C)
We know that
x+7 and y-3 are translation rules of function
so, this is function
