### Scribe

In today's class, Mr. K put us in a group again to do the Inverse Functions Lab. We use parametric mode to graph inverse of the function. Letting X1=T and Y1=f(T). And the inverse of this function can be graphed by letting X2=f(T), and Y2=T. And Finally, control the accuracy of our graph, and values found by tracing along the curve, by changing the size of the step found in the WINDOW menu. a small step will increase the accuracy and the time nessary to draw the graph.

Also we looked over the logarithm function. We know the inverse of the exponential function y=b^x is the logarithm function to the base b. To do the inverse of the function is, we change the input "exponent" to output "exponent" of f(-1)x. and change the output "power" to the input "power" of f(-1)x. We interchange the input (domain) and range of f^-1(x). We didn't finished it today about logarithm function, and I think Mr.K will continues tomorrow and I guess that's all for today's scribe.

Sorry, I am not a good scribe. ;^^*
And Nest Scribe is Ara ;))
