Answer 4

f(2) means evaluate the function at x = 2

Answer 5

For example

Suppose f(x) = x^2
and we had to evaluate f(2)

Then we would take f(x) = x^2 and replace everywhere we see x with 2, then evaluate as follows....

f(2) = 2^2

f(2) = 4

Answer 6

f(2) , here x=2 which is an element in the domain wheras f(x)=2 , that is the y value which is an element from the range.
