Graph Transformations 1 F X

C 0 moves it down.

Graph transformations 1 f x. The basic graph is exactly what it sounds like the graph of the basic function. The y intercept of the graph y 1 f x is given by 1 f 0 which is the reciprocal of y 0. By determining the basic function you can graph the basic graph. Its basic shape is the red coloured graph as shown.

Vertical translation by 5 units upwards. Stretches the graph out and makes it flatter. The basic graph will be used to develop a sketch of the function with its transformations. In this case the vertex for is.

To start let s consider the quadratic function. F x 1 b x compresses the graph and makes it steeper. The absolute value is the distance between a number and zero. Replace the variable with in the expression.

Graph the basic graph. In this case. Tap for more steps. Multiplying the bottom of the function by some value.

We can move it up or down by adding a constant to the y value. The basic graph can be looked at as the foundation for graphing the actual function. To find the coordinate of the vertex set the inside of the absolute value equal to. Graph f x x find the absolute value vertex.

Similarly the old horizontal asymptote y lim x f x 2 will become y lim x 1 f x 1 lim x f x 1 2 since f x is being replaced by 1 f x. Let us start with a function in this case it is f x x 2 but it could be anything. The simplest shift is a vertical shift moving the graph up or down because this transformation involves adding a positive or negative constant to the function in other words we add the same constant to the output value of the function regardless of the input. To move the line down we use a negative value for c.

One simple kind of transformation involves shifting the entire graph of a function up down right or left. C 0 moves it up. G x x 2 c. Y f x becomes y f ax these transformations are called horizontal stretches crunches or dilations they horizontally stretch a 1 or squeeze a 1 the graph of the given function.

Mr jeffery demonstrating an easy trick that will allow you to work out graph transformation questions using a simple to follow method. Furthermore notice that there are three similar graphs blue coloured that are transformations of the original.
