Functions And Their Graphs. Nov 05 2011 determine whether the points on this graph represent a function now just as a refresher a function is really just an association between members of a set that we call the domain and members of a set that we call a range so if I take any member of the domain lets call that X and I give it to the function the function should tell me what member of my range is that associated with it so it should point to some other value this is a function it would not be a function. X 0 1 4 9 fx 0 1 2 3.
Also for a 1 the function Pt b is called a constant function and its graph is a horizontal line. The graphs of the original and inverse functions are symmetric about the line y x. Functions are graphed on the coordinate plane.
In this setting we often describe a function using the rule y fx and create a graph of that function by plotting the ordered pairs xfx on the Cartesian Plane.
The graph of functions helps you visualize the function given in algebraic form. We shall always take the radian measure of the angle as the argument input x ie the value of y sin x at.
