We evaluate the inside function first and then use the output of the inside function as the input to the outside function. Details of expression syntax see below. Use the hatch symbol # as the variable when inputting For example, f(x) is read âf of xâ and means âthe output of the function f when the input is xâ. Another example is something like g(2). This is read âg of 2â and represents the output of the function gfor the input value of 2. Notice that, to evaluate the function in table form, we identify the input value and the corresponding output value from the pertinent row of the table. Function notation is written using the name of the function and the value you want to find the output for. Type in any function above then use the table below to input any value to determine the output: Note: The answer above, y = â3 when x = 0, means that the point (0, â3) is on the graph of the equation y = 4x â 3.
