How do we evaluate functions
WebWhen we have a function in formula form, it is usually a simple matter to evaluate the function. For example, the function f(x) = 5 − 3x2 can be evaluated by squaring the input value, multiplying by 3, and then subtracting the product from 5. How To Given the formula for a function, evaluate.
