Graphing and Analyzing Functions on the TI-84

The video tutorial explains how to graph functions on a TI-84 calculator, focusing on f(x) = 2^x, g(x) = log base 2 of x, and h(x) = x. It covers entering functions into the calculator, graphing them, and using the table of values to find specific points. The tutorial highlights the symmetry between f(x) and g(x) across the line y = x, demonstrating that they are inverse functions.

What are the three functions that need to be graphed on the TI-84 calculator?

• f(x) = x^2, g(x) = log base 10 of x, h(x) = x

• f(x) = 2^x, g(x) = log base 2 of x, h(x) = x

• f(x) = 3^x, g(x) = log base 3 of x, h(x) = x

• f(x) = x^3, g(x) = log base 5 of x, h(x) = x
