The expression "f (x)" means "a formula, named f, has x as its input variable" It does not mean "multiply f and x"! What does F x mean in a graph?The graph of the function is the set of all points (x,y) ( x, y) in the plane that satisfies the equation y= f (x) y = f ( x) If the function is defined for only a few input values, then the graph of the function is only a few points, where the x coordinate of each point is an input value and the y coordinate of each point is the
