When it says f(4) that means x=4
So you then just fill in all the x’s with 4’s and solve as normal
963 would be rounded to become 1000.
This is because 9 is the first non-zero number and so since there are only going to be 1 significant figures, the 9 would round up or down. There is a 6 after the 9, so it rounds up to 10, making it 1000.
