Answer:

What is the effect of changing the values of a, h and k in graphing quadratic function?

The basic quadratic function: f(x) = x^2

The basic cubic function: f(x) = x^3

The basic absolute value function:  f(x) = |x|

The basic square root function: y = sqrt(x)

In each of these functions, you will investigate what the parameters "a", "h", & "k" will do to the graph the parent function y = f(x) when we graph the function y = a*f(x - h) + k

The following applet allows you to use a slider to change the values of different parameters of 4 key functions.  The parameters are "a", "h", and "k".  

Within the following applet, change the slider values for "a", "h", and "k".  

As you do, pay attention to how the equation of the graph changes as you use the slider to change a certain parameter.
