Test graph for inverse function | (f*f')(x)=x and (f'*f)(x)=x |
Example of Inverse Function (Using previous card) | f'={(0,1),(-2,7),(-6,3),(4,4)} |
Example of one-to-one | f={(1,0),(7,-2),(3,-6),(4,4)} |
Solve by graphing | A function can be tested using the horizontal line test. If a horizontal line passes through the graph only one time, the function is one-to-one. |
One-to-one | Each input corresponds to one output, and one output corresponds to one input. |
Inverse Function | To get the inverse of a one-to-one functions, simply switch the inputs and outputs in each ordered pair. |
f(x)=2/5x+12 | f^-1(x)=2-12x/5x |
f(x)=x-7/11 | f^-1(x)=11+7x |
f(x)=1/2x+3 | f^-1(x)=2x-6 |
f(x)=4x+8 | f^-1(x)=x-8/4 |
