f(x) is read is function f of x.

Where x is the input variable and function f(x) gives output value of function for x input value.

For the given function, we have f(3).

If we compare f(3) by f(x), the x represented by input value 3.

Therefore, x value is 3 there.

And we also have f(x) =-5.

Because function value is -5. So we can read it as, "for x input value of the the function gives output value -5."

For the asked value of x is just x=3.
