Someone help i'm doing a test now and ima fail help

I think first option is correct.

f(x)=x-3

if x=0,then

f(0)=0-3=-3

if x=3,then

f(3)=3-3=0

points={0,-3},{3,0} that is in question

tube or goog would be a great resource to with that question

step-by-step explanation:

a child is 12 years old, and his father is 32 years older. in how many years will the age of the father be 2 times the age of the child?

******************

this needs to be the answer format, or else your answer is incomplete.

if the number of years is x, then the equation is

in __ years
