The graph of function f is defined as the set of all points (x, f( where x is in the domain of f

true
false

True

Step-by-step explanation:

The graph of function f is defined as the set of all points (x,f(x)).

f(x) is defined a function with input variable x.

We can write all the points on f(x) as (x,y)  where y=f(x).

We always write x value first and y value second in coordinate system.

As we know x is input value or independent variable.

So, It would be domain of function.

y is output value of function or dependent variable.

So, It would be range of function.

Hence, The set of all points (x,f(x)) where x is domain of f(x).
