To change the functions, select either f(x) or g(x) i n the algebra view. Double click and then edit the function. Since they are dynamically linked, the graphics screens will change as well. Are the following pairs of functions inverses of each other? (These are also listed in Q70 in your text.) 1. f(x) = sqrt(x) and g(x) = x^2 2. f(x) = 3x and g(x) = (1/3)x 3. f(x) = 2x+5 and g(x) = .5(x-5) 4. f(x) = 1/x and g(x) = x 5. f(x) = (x)/(x+2) and g(x)=(2x)/(1-x)
How can you determine whether or not they are inverses based on the DynaGraph? Based on the Cartisian graph? Without using either representation?
