Answer 1

just plug it in...

Answer 2

Plug in 2 for x because it is your x-value.
If someone asks to plug in something for f(x) and gives you x, you automatically plug in the value of x into f(x). Does that make sense?

Answer 3

Then you just solve this Q like a normal expression.

Answer 4

Show me how you'd plug in 2 for x please :)

Answer 5

Find f(2) if f(x) = (x + 1)^2.

f(2) is short for "replace x with 2" and do the arithmetic
in other words, erase the x and put 2 in its place, like this
(2+1)^2

do you remember "order of operations" ?
first do the the "stuff" in the parens. what is 2+1 ?
