Question

is this correct

3x-3=0
3x-3+0=0
3x-3=0

f(x)=3x-3

table:
1 f(1)=3(1)-3 so it will be (1,0)
-1 f(-1)=3(-1)-3 so it will be (-1,-6)
2 f(-2)= 3(-2)-3 so it will be(-2,-9)

what are some videos i can watch that sums up this equation?

Answer 1

in
"is this correct

3x-3=0
3x-3+0=0
3x-3=0 "

you really haven't done anything
were you "solving" 3x-3 = 0 ??
then
3x-3=0
3x=3
x = 1

you then simply state
f(x) = 3x-3
Is that somehow related to the first part other than by appearance ?

2 f(-2) = 3(-2) - 3 so it will be (-2,-9)
is really "bad form" in mathematics and reminds me of a run-on sentence in English grammar

What is the "it" in that expression?
What is the "2" in front of f(x) ?
normally that would mean 2 times f(x) .

sorry to be so critical, but Mathematics is a very precise language.
(your actual calculations are correct, I just don't like the way you state them)
