How to evaluate a function for a given value

👉 Learn how to evaluate a function and for any given value. For any function, f(x) x is called the input value or the argument of the function. To evaluate a function, all we have to do is to change the argument of the function from x to the new given argument. We do this by "plugging in" the value into the input variable of the function and then simplifying it.

Why can I learn from this but when my teachers teach me something it goes in one ear and out the others

What if there is no given function equation? There is only a graph with two functions and all that is given is f(x) for one line and g(x) for the other. I have to evaluate the function at given x values as well.
